Question

Question 19 (1 point) (03.06 LC) Choose the equation below that represents the line passing through the point (−3, −1) with a slope of 4. (1 point) a y − 1 = 4(x − 3) b y + 1 = 4(x + 3) c y − 3 = 4(x + 1) d y + 3 = 4(x − 1)

Answer 1

y + 1 = 4(x + 3)

Explanation:

Answer 2

The point-slope form:

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

We have a slope m = 4 and the point (-3, -1). Substitute:

`y-(-1)=4(x-(-3))\\\\\boxed{y+1=4(x+3)}\to\boxed{b}`
