Answer: y-3=4(x+1) in point-slope form and y=4x+7 in slope intercept form

Explanation:

You can find the point-slope form by plugging the numbers into the following: y-y₁=m(x-x₁).

You will end up with y-(3)=(4)(x-(-1)) which when simplified equals y-3=4(x+1).

To find slope intercept form you know need to isolate y and simplify.

Adding 3 to both sides results in y=4(x+1)+3.

If you then distribute you get y=4x+4+3 which simplifies to y=4x+7.
