Question

A line passes through the points (–6, 4) and (–2, 2). Which is the equation of the line?
y = negative one-half x + 1
y = one-half x + 7
y = –2x – 8
y = 2x + 16

Answer 1

Answer:

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

Step-by-step explanation:

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

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

~~~~~~~

m = $\frac{4 - 2}{- 6 + 2 }$ = - $\frac{1}{2}$

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

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

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