Question

Choose the equation below that represents the line passing through the point (−3, −1) with a slope of 4. (1 point)

y − 1 = 4(x − 3)

y + 1 = 4(x + 3)

y − 3 = 4(x + 1)

y + 3 = 4(x − 1)

Answer 1

It would be the first one

Answer 2

The equation of a line is written using the form y - y1 = m(x-x1), where m is the slope and y1 and x1 are points on the line.

You are given the point (-3,-1) which means x1 = -3 and y1 = -1.

You are also told the slope is 4.

Replace those in the equation :

y - (-1) = 4(x-(-3)

simplify:

y+1 = 4(x+3)
