This week in Math 10 we started a new unit of “Linear Relations.” It was mostly a review from last year but we learned how to use x and y intercepts in graphing. We use the x and y intercepts when we need to find out what y is when x is zero or what x is when y is zero. Using the x and y intercept is super simple, all you do is to find x, you set y as 0 and solve for x, and the opposite for finding y. In this example were trying to find x and y from 3y = 5x + 15. First we’ll calculate the one on the left, x if y is zero. We start off by writing the equation we’re using which is 3y = 5x + 15, then we replace y with zero. Now we solve for x by removing 3(0) and bringing 15 to the opposite side which makes it -15. Then isolate x by dividing each side by 5 and we end up getting -3 = x. For the right side, y if x is zero we can start the same way, by replacing x with 0. Then we just isolate y by removing 5(0) and diving each side by 3 so we end up with y = 5.
