Question

Which of the function rules below would result in the following graph? On a coordinate plane, a line goes through (2, 2) and (6, 4). a. y = 0.5 x + 1 c. y = 2 x + 1 b. y = 0.5 x minus 1 d. y = two-thirds x + 1 Please select the best answer from the choices provided A B C D

Answer 1

A)

m= (y2-y1)/(x2-x1)= 0.5
y=mx+b
At point (2,2)
2=0.5*2+b
=b=2
So, equation is
y=0.5x+1
