Question

The graph is a line that passes trough the coordinates (2, 11) and (8, 14). Which is an equation in terms of x and y for this function?

A. y = 1/2 x + 10
B. y = 2/3 x + 9
C. y = 3/2 x + 8
D. y = 2x + 7

Answer 1

Answer:A

Explanation:

m=(14-11)/(8-2)

m=3/6

m=1/2

y = 1/2x+b substitute one of the points

11=1/2(2)+b

11=1 + b

b=10

y = 1/2x+10
