Answer: x-int: (-7/4, 0)
y-int: (0, 7)
Step-by-step explanation: In slope intercept form y=mx+b, b is the y-int, so we already have that as 7. The y intercept is when x=0, so it is (0,7). For the x-intercept, we must find when y=0, so we can substitute 0 for y in the equation.
>y=4x+7
>0=4x+7
>4x=-7
>x=-7/4
so x-int = (-7/4, 0)
