HELP PLEASE

Choose the equation that Choose the equation that represents a line that passes through points (-6, 4) and (2,0)

A. x + 2y = 2

B. 2x - y = -16

C. x + 2y = -8

D. 2x + y = 4

Answer 1

A

Explanation:

m = (0 - 4) / [(2 - (-6)]

= -4 / 8

= -1/2

Use (-6, 4) to find for b:

y = mx + b

4 = -1/2 (-6) + b

4 = 3 + b

4 - 3 = b

1 = b

Therefore the equation is:

y = mx + b

y = -1/2 x + 1

or 2y = -x + 2
