A line passes through the points (5, –7.5) and has a y-intercept 10. Which is a linear function in the form of y = mx + b for this line?
A. y = 0.5x + 10
B. y = –1.5x + 10
C. y = –3.5x + 10
D. y = 10x – 3.5

y = -3.5x + 10 so C.

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
