y-intercept is the constant -2
Slope is the coefficient of xx which is 3

Explanation:

consider the standard form y=mx+cy=mx+c where m is the slope (gradient).

Comparing to y=3x-2y=3x2 we find by that the slope m = 3m=3

The y-intercept is when the graph crosses the y-axis. The y axis is at x=0x=0 so we substitute x=0x=0 and we get:

y=3(0)-2y=3(0)2

y=-2y=2

So the y-intercept is the constant - 2
