The slope of the line that passes through the points (-10,y) and (5, 2) is 2/5. What is the value of y?

Murrr4er [49]

Answer:

C, -4

Step-by-step explanation:

slope=change in y/change in x

$\frac{2 - y}{5 - ( - 10)} = \frac{2}{5}$

$\frac{2 - y}{5 + 10} = \frac{2}{5}$

multiply both sides by 2/5

$2 - y = \frac{2}{5} (5 + 10)$

simplify the right side. 2/5 × 5 = 2 and 2/5 × 10 = 4

$2 - y = 2 + 4$

$2 - y = 6$

bring y to the other side by adding y on both sides

$2 = 6 + y$

subtract 6 on both sides

$2 - 6 = y$

so y is -4
