Answer:

To find the x-intercept, make #y# equal to zero, and solve for #x#. To find the y-intercept, make #x# equal to zero, and solve for #y#.

Explanation:

#y=4x-2#

X-Intercept

#0=4x-2#

Add #2# to both sides of the equation.

#2=4x#

Divide both sides by #4#.

#2/4=x#

Simplify.

#1/2=x#

Switch sides.

#x=1/2#

Y-Intercept

#y=4(0)-2#

#y=-2#

graph{y=4x-2 [-12.98, 12.33, -7.64, 5.02]}
