Pls help i forgot how to do this

x=6

Step-by-step explanation:

We can use the slope formula

m = ( y2-y1)/(x2-x1)

-2 = (-13- -9)/(x - 4)

-2 = (-13+9)/(x-4)

-2 = (-4)/(x-4)

Multiply each side by x-4

-2(x-4) = -4

Divide each side by -2

x-4 = -4/-2

x-4 = 2

Add 4

x-4+4 = 2+4

x=6

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
