How do I solve for this? will give points

y = -1 is the equation of a horizontal line that passes through every point with -1 as its y-coordinate. In other words, every point on the line takes the form (x, -1).

A line perpendicular to this one would be vertical, so that the x-coordinate is now fixed. If this line passes through (8, -4), then for every possible y-coordinate, the x-coordinate is fixed to be 8. So every point on the line takes the form (8, y), and the equation for this line is x = 8.

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
