Question

Write an equation for a line passing through the points (-1, 8) and (0, 5).

Answer 1

Answer:

y=-3x+5

Step-by-step explanation:

y=mx+c

point 1: (-1;8)

point 2: (0;5)

$m = \frac{y2 - y1}{x2 - x1}$

$m = \frac{5 - 8}{0 - ( - 1)}$

$m = - \frac{ 3}{1}$

$m = - 3$

subs point and gradient to get c

5=-3(0)+c

Therefore c=5

The equation is y=-3x+5
