y = -8

Work Step by Step

The line is horizontal, so the slope is equal to 0. Therefore in the equation y= mx+b, m = 0. b is the y-intercept, and since the slope is 0 all values of x have the same value for y. So at x=2, y=-8. y will equal -8 for all values of x including 1=0, the y-intercept. Therefore, b= -8, and the answer is: y= 0x-8 or y=-8.
