Question

Which equation represents the following graph?

A.) Y = 2/3 x + 2

B.) Y = 3/2 x + 2

C.) Y = 2/3 x – 2

D.) Y = -2/3 x + 2

Answer 1

The answer would be A.) because the rise would be 2 and the run would be 3. It is going through 2 on the y axis so your answer is 2/3 + 2.

Answer 2

Y intercept (0, 2) so b = 2

Slope = (2 - 0) / (0 + 3) = 2/3

Equation y =  mx + b

In this case slope m = 2/3 and y intercept = b = 2

So equation y = 2/3 x + 2

Answer

A.) Y = 2/3 x + 2
