Question

What is the point-slope form of a line that has a slope of –4 and passes through the point (–3, 1)?

y minus (negative 3) = negative 4 (x minus 1)
y minus 1 = negative 4 left-bracket x minus (negative 3) right-bracket
Negative 1 minus y 1 = negative 4 (negative 3 minus x 1)
3 minus y 1 = negative 4 (1 minus x 1)

Answer 1

y = -4x - 11

Explanation:

Following the equation y - y1 = m(x - x1) we get y - 1 = -4(x + 3)

After multiplying we get y -1 = -4x - 12

Add 1 to both sides to get y by itself

You get y = -4x - 11
