Write the equation of each line slope of -4 and goes through the point (2,-3)

Start by substituting the slope of  into slope-intercept form, which is , where m is the slope:



Now, we'll use the given point to find b by substituting for x and y. The given point is (2, -3), so x=2 and y=-3:



Now add -8 to both sides to get:



Now, put it all together:

Horizontal change or the change of x
