What is the intercepts of y=4x-2

Simple,

The Y inctercept.

To find the Y intercept we know x=0 because the graph crosses the y axis when x axis is 0 so.

Y=4x-2

Y=4 (0) - 2

Y=-2 y interecpt is - 2

The x intercept.

To find the X intercept we know y=0 because the graph crosses the x axis when y axis is 0 so.

Y=4x-2

0=4x-2

2=4x

2/4 = x x intercept is 2/4 or 0.5
