Oe scored f points on his video game. Sally scored 950 points when she played the same game. Their combined score was y points. Write an equation relating f and y.

f = the number of points Oe scored

y = Oe and Sally's score combined

f + 950 = y

[Oe's score(f) + Sally's score = their combined score(y)]

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

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
