Last week, I explained the y=mx+b formula and how it comes in handy. Well, this week, I am going to explain the steps to graphing a line in the y=mx+b form. Let's use the equation y=2x+7. In order to graph this line, you would need to use the steps in graphing equations in this form.
Now, the first thing you do when you have an equation in this form is look at the number in the b spot. That number is the y-intercept on the graph. Next, you would look at the m spot and that number represents the slope. So, in this problem, you would go up 2 spaces, and over 1 space since 2/1 is the same as 2. Now, you can plug in any of the points on the line that you just graphed. Plug in the x and the y in their spots in the equation and that'll prove your line correct or incorrect. Well that's all for today, so see ya later!
