-9

Step-by-step explanation:

Slope = rise/run = (y1 - y2)/(x1 - x2)

Therefore:

Slope = (7 - (-9))/(-5 - w)

4 = (7 + 9)/(-5 - w)

4(-5 - w) = 16

-20 - 4w = 16

4w = -20 - 16

4w = -36

w = -36/4

w = -9

step-by-step explanation:

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
