This week in math 10 an important thing we learned was the equation y = mx + b

It represents the y-intercept form. y is the output number, m is the slope, x is the variable for m and b is the y-intercept.

For example, in this form, we could have y = 5x + 9

5 is the slope and 9 is the y-intercept.

One last equation is m(x-x1) = y – y1

this is for the equal point-slope form.

So the x is on the x-axis and the y is for the y axis. For example, if a line has a slope of 6 and goes through the coordinates (6,8), your equation should look like this:

6(x – 6) = y – 8
