The x-intercept occurs at the point where y = 0
So, plug y = 0 into the equation to get: 3x + 2(0) = 6
Solve to get x = 2
So, the x-intercept is 2

The y-intercept occurs at the point where x = 0
So, plug x = 0 into the equation to get: 3(0) + 2y = 6
Solve to get y = 3
So, the y-intercept is 3

What is the sum of the x intercept and y intercept of this line?
Sum = 2 + 3 = 5

Answer: D

Cheers,
Brent
