Very easy to generate if you know a point on the line, or if you know a point that satisfies, where the X and Y coordinates So let's first thinkĪbout point-slope form. And I encourage you, like always, pause the video and see if you can do it. In both point-slope form and in slope-intercept form. Now what I want to do in this video is I want to say, well can weįind that linear equation and can we express it Represents all of the solutions to this linear equation. Now let's say we also know, we also know that when X is equal to six Y is equal to one. We have a linear equation and we know when X is equal to four that Y is equal to nine and we've plotted that I hope that this helped! I have never answered a question before, so I'm sorry if this answer seemed to go on forever. So you would set up the slope equation like so: So now you know that there is no y-intercept in this problem. To find slope you would do the following: Remember, it is change in Y over change in X because you need to find the independent variable for the slope. I bought 2 ornaments, so my points for the graph would be the following: Otherwise, you would be searching for Y, and you already know what it is. That is why you always do change in Y over change in X. So you already know what the dependent variable is. The dependent variable is the amount of money because it changes depending on the amount of ornaments. Every ornament I buy increases the amount of money I spend by $2. So say for example that I am looking for christmas tree ornaments. So when you are finding slope, you are trying to find the rate of change of the independent variable. If you want to customize the colors, size, and more to better fit your site, then pricing starts at just $29.99 for a one time purchase.It is not the change in X over the change in Y because X is always the independent variable in the situation, and Y is always the dependent variable in the situation. You can get a free online slope intercept form calculator for your website and you don't even have to download the slope intercept form calculator - you can just copy and paste! The slope intercept form calculator exactly as you see it above is 100% free for you to use. Add a Free Slope Intercept Form Calculator Widget to Your Site! Let's be honest - sometimes the best slope intercept form calculator is the one that is easy to use and doesn't require us to even know what the slope intercept form formula is in the first place! But if you want to know the exact formula for calculating slope intercept form then please check out the "Formula" box above. The final step is to have a webpage to host the unique Slope Intercept Form Calculator.Īlso be sure to check out the Slope Calculator here on. The code contains all the changes in color, width, and font size that were made in the previous sections. When all the specifications have been made, the user can copy and paste the JavaScript code that is generated at the bottom of the page. Like the former two options, the font size is shown immediately in the sample. Font sizes from 10 to 20 pixels are available in a drop box. The last change that can be made is the font size that will be used for the title, slope, and y-intercept headers. When the width changes on the slider the reality is reflected directly in the sample. As with the color choices, this slider immediately affects the sample. This allows for a selection of widths between 2 pixels. Once again, Calculator Pro makes this process easy by providing a slider bar that can be moved across the page. The width of the Slope Intercept Form Calculator can also be changed. This makes it easy to sample different color combinations without having to guess whether or not it will look good as a whole. Once a new color is selected, the sample changes to match the user’s choice. Not only is it possible to select and save each color choice, a live sample is shown directly beneath the color selections. This same process can be repeated with the border color and text color. Then, a cursor can be moved to select, for instance, a darker or lighter red or yellow. A slider bar is used to select the basic hue, everything from black to white. Clicking on the background color menu causes a box to pop up where a pallet of colors is shown. Customizing the Background Colorįirst, a background color can be specified. They do much more by allowing the user to customize the look and feel of each script. These values are then placed within the slope-intercept form, y = mx + b, and shown to the user.Īs an example, if the user were to state that m equals 5 and b equals 12 then the output of the calculator would return y = 5x + 12.Ĭalculator Pro does not just hand over a script to be copied and pasted directly into one’s website. It takes two inputs, the slope and the y-intercept, and runs it through a bit of code. One, of the mathematics formula variety, is the Slope Intercept Form Calculator.
