Question

What is the equation of the following line?

A. y=-1/2x-1
B. y=2x+1
C. y=1/2x+1
D. y=-2x+1

Answer 1

B

Answer 2

The y-intercept is (0,1)

so b = 1

you then go up 2 and to the right one unit to get to the next point (1, 3)

so that shows you that the slope is 2/1 = 2

that explains why m = 2

put this together to get

y = mx+b

y = 2x + 1
