Find the slope of a line parallel to a line that contains the points (8, -3) and (2, 5).

Illusion [34]

Answer:

$-\frac{4}{3}$ (Your answer choices were really confusing, so I just put the plain answer)

Step-by-step explanation:

To find the slope of a line with just two points, we can use the formula $\frac{y2-y1}{x2-x1}$ . In this case, $\frac{5-(-3)}{2-8}$ . This is $\frac{8}{-6}$ . This reduces to $-\frac{4}{3}$
