Question

Find the value of x so that the points (-2,5) and (8x) lie on a line with a slope of -3/5.

a) x = -1
b) x = 1
c) x = -2
d) x = 2

Answer 1

To find the value of x so that the points (-2,5) and (8x) lie on a line with a slope of -3/5, use the formula for slope. Solve the equation (5 - 8x) / (-2 - 8) = -3/5 to find the value of x.

Step-by-step explanation:

To find the value of x so that the points (-2,5) and (8x) lie on a line with a slope of -3/5, we can use the formula for slope. The formula is (y2 - y1)/(x2 - x1), where (x1, y1) and (x2, y2) are the coordinates of the two points.

Using the given points (-2,5) and (8x), we have:

(5 - 8x) / (-2 - 8) = -3/5.

Solving this equation for x will give us the value we're looking for.
