Question

What is the equation of a line with a slope of 1/2 that passes through the point, (-2, -4)?

Answer 1

B

Explanation:

y = mx + b where m = slope and b = y intercept.

The slope = 1/2 so you can eliminate C.

You can plug (-2,-4) into each equation and see which one works.

OR

y = 1/2x + b

Plug in (-2,-4) for (x,y) and solve for b.

-4 = 1/2(-2) + b

-4 = -1 + b

-3 = b.

So the equation would be y = 1/2x - 3. B
