Question

Which equation represents a line that passes though (-9,-3) and has a slope of -6

Answer 1

Answer:

D

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

here m = - 6 and (a, b) = (- 9, - 3), thus

y - (- 3) = - 6(x - (- 9)), that is

y + 3 = - 6(x + 9)

Answer 2

D) y + 3 = -6(x + 9)



The equation for point-slope form is y - y1 = m(x - x1) where (x1, y1) is a point and m is the slope.

Substitute the values in to get y - (-3) = -6(x - (-9)).

Now, simplify a little bit.

y + 3 = -6(x + 9)

There’s the answer.
