Question

Find an equation in slope-intercept form of the line that has slope 4 and passes through point A(3,-4)

a. y= 4x -16
b.y= -4x -16
c.y= 16x - 4
d.y= 4x + 16

Answer 1

m = 4
(x₁, y₁) = (3,-4)

The equation
y - y₁ = m(x - x₁)
y - (-4) = 4(x - 3)
y + 4 = 4x - 12
y = 4x - 12 - 4
y = 4x - 16

the answer is a

Answer 2

answer will be
c
y=16x-4
