Question

Which equation matches the function shown below?

Answer 1

Answer:

Step-by-step explanation:

Pick the two easiest points to deal with.

(0,4)  and (2,0)

Find m

m = (y2 - y1)/(x2 - x1)

y2 = 4

y1 = 0

x2 =0

x1 = -2

m = (4 - 0)/(0 - - 2)

m = 4/2 = 2

Now use one of the points to find b

y = mx + b        Use (0,4)

4 = 2*0 + b

b = 4

The equation you want is y = 2x + 4
