Question

A line has a slope of −5 and contains the point (−2, 4).



Which equations represent the line?



Choose all answers that are correct.









A.

−5x + y = −6








B.

5x + y = −6








C. (y-4)=-5(x+2)









D.

(y + 4) = −5(x − 2)

Answer 1

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

Where y1 = y-value
Where x1 = x-value
Where m = slope

Answer 2

A line has a slope of −5 and contains the point (−2, 4).


We can use the formula y - y1 = m(x - x1)

Where m = -5
-y1 = 4
and -x1 = -2

Answer 3

So A and C?

Answer 5

Well, not exactly for A they're trying to trick you, because it's not in the correct form, you actually have to add 5 to both sides to get it into the correct form:

\(-5x + y = 6\)

Add 5x to both sides:

\(y = 5x + 6\)

So the slope of A, is 5, not -5, so it can't be an answer.

Answer 6

C is correct :)

Answer 7

so B and C?
