What is an equation of the line that passes through the points (-2, 1) and (-8, 4)?
Grace [21]

Answer:

<h2>3x + 6y = 0</h2>

Step-by-step explanation:

Equation of a line = y = mx + c

where m = slope

m = (1 - 4) / (-2 - (-8))

<h3>m = -3 / 6</h3>

y - 1 = -3/6 (x + 2)

6y - 6 = -3x - 6

3x + 6y = 0
