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?

Answer 1

Answer:

a = - 6

Step-by-step explanation:

y - $y_{1}$ = m(x - $x_{1}$)

y - (- 2) = $\frac{1}{2}$ (x - 4)

y + 2 = $\frac{1}{2}$ x - 2

y = $\frac{1}{2}$ x - 4

y = $\frac{1}{2}$ ( - 4) - 4 = - 6

(- 4 , - 6)
