To get your answer we'll plug 0 in for x into the equation.
So, multiply 4*0 which equals 0.

Then we'll add 0 and 7 which leaves us with
The y-intercept of this equation is:

To find the x-intercept of this equation we'll rewrite it as

Then we'll subtract 7 from both sides,

Now we'll divide each side by 4. Then simplify which brings us to our answer,
The x-intercept of this equation is:
