Find the slope between points (-5, 8) and (4,-7).

the slope is (-1,3)

Step-by-step explanation:

The equation to find slope from two points on a line is m = , where

(x1,xy1) is one point (x2, y2)  is the other point.

let (5, -8) be point 1

let (4, -7) be point 2

Substitute the given values into the equation.

keep simplifying then you will get the answer (-1,3)

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
