Write the equation of the line that passes through (-2,0) and (0, -7)

y= -3.5x-7

Step-by-step explanation:

insert (-2,0), (0,-7) into the equation y=ax+b

=> 0= -2a+b, -7=b

solve a, b

=> -2a-7=0

=> -2a=7

=> a= -3.5, b= -7

insert a, b into the equation y=ax+b

y= -3.5x-7

50.6

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
