The x-intercept is (0,0)(0,0).

The y-intercept is (0,0)(0,0).

This means that the line passes through the origin.

Explanation:

The x-intercept is the value of xx when y=0y=0.

Substitute 00 for yy and solve for xx.

0=2x0=2x

Divide both sides by 00.

0/2=(2x)/x02=2xx

Simplify.

0=x0=x

x-intercept: (0,0)(0,0)

The y-intercept is the value of yy when x=0x=0.

Substitute 00 for xx and solve for yy.

y=2(0)y=2(0)

Simplify.

y=0y=0

y-intercept: (0,0)(0,0)
