the line of a function passes through the points indicated what is the x- intercept of this function? x/0/2/4/6 - y/-1/0/1/2

1 answer:

5 0

(0,-1)(2,0)
slope = (0 - (-1) / (2 - 0) = 1/2

y = mx + b
-1 = 1/2(0) + b
-1 = b

ur equation is : y = 1/2x - 1

ur x intercept can be found by subbing in 0 for y and solving for x
0 = 1/2x - 1
-1/2x = -1
x = 2.....or (2,0) <== ur x intercept
