Answer:

y = 2/7 x - 51/7

Step-by-step explanation:

Equation of the line

(y-y1)/(y2-y1) = (x-x1)/(x2-x1)

(y-(-7)/(-9-(-7) = (x-1)/(-6-1)

(y+7)/-2 = (x-1)/-7

(-y-7)/2 = (-x+1)/7

-y-7 = -2/7 x + 2/7

-y = -2/7x +2/7 + 7

y = 2/7 x - 2/7 - 7

y = 2/7 x + (-2-49)/7

y = 2/7 x - 51/7

Answer:

Step-by-step explanation:

$slope = \frac{w - 2}{0 - ( - 1)} \\ \\ \therefore \: 6 = \frac{w - 2}{0 + 1} \\ \\ \therefore \: 6 = \frac{w - 2}{1} \\ \\ \therefore \:w - 2 = 6 \\ \\ \therefore \:w = 6 + 2 \\ \\ \therefore \:w = 8\\ \\$
