Answer:
y = (2/3)x + 9
Step-by-step explanation:
Equation of a straight line is y = mx + b. You are trying to finish the equation.
Note that:
m = slope = 2/3
b = y-intercept = 9
Plug in the corresponding numbers to the corresponding variables:
y = mx + b --> y = (2/3)x + 9
y = (2/3)x + 9 is your equation.
