Answer: y-7 = 4(x+3), choice B
============================================
Point slope form is generally
y-y1 = m(x-x1)
we have m as the slope and (x1,y1) as the point this line goes through. In this case,
m = 4
(x1,y1) = (-3,7) so x1 = -3 and y1 = 7
So,
y-y1 = m(x-x1)
y - 7 = 4(x - (-3))
y - 7 = 4(x + 3)
which is why choice B is the answer
Answer:

Step-by-step explanation:
The y-intercept is where x is 0 (0,y)
The x-intercept is where y is 0 (x,0)
Insert 0 as the value for x to find the corresponding y value:

Simplify multiplication:

Isolate the variable. Divide both sides by 4:

Make the variable positive. Multiply both sides by -1:

The y-intercept is at
.
Insert 0 as the value for y to determine the value of x:

Simplify multiplication:

Isolate x. Divide both sides by 5:

Multiply both sides by -1:

The x-intercept is at
