Question

choose the equation below that represents the line passing through the point (2,-4) with a slope of 1/2

Answer 1

In order to find this, you use the y=mx+b formula. Your are given the slope so you know that you can say y=1/2x+b. Now you plug in the point (2,-4). The problem would be -4=1/2(2)+b. When you solve it, you get -5=b. Therefore, the equation is: y=1/2x-5
