Question

Please help and explain.

Answer 1

-(1/3)

Explanation:

The answer is negative 1/3. Slope is the change in y divided by the change in x. Given two points, (4,8) and (7,7), the slope is negative 1/3

Answer 2

-1/3

Explanation:

Use the formula, (y2 - y1)/(x2 - x1). In this case, there is a negative slope.

Start from point, (1, 9) and go to point (4, 8).

Use the formula:

(y2 - y1)/(x2 - x1)

Y2 = 8

Y1 = 4

X2 = 9

X1 = 1

(8 - 9)/(4 - 1) = -1/3

Therefore, the slope is -1/3
