Question

A line passes through the point (4, –2) and has a slope of One-half.

A coordinate plane.

What is the value of a if the point (–4, a) is also on the line?
–6
–5
5
6

Answer 1

-6

Explanation:

Answer 2

a = -6

Explanation:

The given line in point-slope form is y + 2 = (1/2)(x - 4).

Replacing x with -4 yields y + 2 = (1/2)(-4 - 4) = (1/2)(-8)

Then y + 2 = -4, and so y = -6, or a = - 6.
