Answer:

If by 3x2 you meant 3(2), then the y-intercept is 1.

Explanation:

We need to start by simplifying the equation.

y = 3(2) + 2x - 5

y = 6 + 2x - 5

y = 2x + 6 - 5

y = 2x + 1

The "2x" part tells us the growth rate, or slope, of the line, and the "+ 1" is the y-intercept.

Hope this helped!
