Answer:

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

Explanation:

#y=3x-3#

X-Intercept

#0=3x-3#

Add #3# to both sides.

#3=3x#

Divide both sides by #3#.

#1=x#

Switch sides.

#x=1#

Y-Intercept

#y=3(0)-3#

#y=-3#

graph{y=3x-3 [-12.87, 12.44, -7.24, 5.42]}
