Question

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

A.y-(-3)=-4(x-1)
B.y-1=-4[x-(-3)]
C.-1-y there is a 1 under and next to the y=-4(-3-x 1 under)
D.3-y 1 under=-4(1-x 1 under)

Answer 1

The correct answer is A.

Answer 2

The correct option is B.

Explanation:

The point slope from of a line is

`y-y_1=m(x-x_1)`

Where, m is the slope of the line.

It is given that slope of the line is -4 and passes through point (–3, 1).

The equation of line is

`y-1=-4[x-(-3)]`

Therefore option B is correct.
