X=-2

Step-by-step explanation:

If the equation in slope-intercept form is y = (3/2) x+3, you have to make y=0. So, you look for the value of x that makes y=0. To do this, just isolate (3/2) x. Since there is a + 3 in this equation, (3/2) x has to equal - 3 to make y=0. So divide - 3 by 1.5 and that leaves you with x=-2. To make sure that your answer is correct, just substitute it for x.

y = (3/2) (-2) + 3

y = (1.5) (-2) + 3

Multiply 1.5 and - 2

y = (-3) + 3

y=0

So your x-intercept is - 2
