Question

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

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

Answer 1

Answer:

The answer of this questioni is -6

Answer 2

Answer:

a = - 6

Step-by-step explanation:

m = $\frac{y_{2} -y_{1} }{x_{2} -x_{1} }$

$\frac{1}{2}$ = $\frac{-2-a}{4 +4}$

- 2(2 + a) = 8

- 4 - 2a = 8 ⇔ - 2 - a = 4 ⇒ a = - 6
