10. raquel earned $105 for baking
7 pies. the following week she
earned $60 for baking 4 pies.
(a) write an equation raquel can
use to find out how much she will
earn if she bakes x number of pies.
(b) then find out how many pies
she must make to earn $165.

Step-by-step explanation:

(7,105) , (4,60)

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

slope = (60 - 105) / (4 - 7) = -45/-3 = 15

y = mx + b

slope(m) = 15

(4,60)...x = 4 and y = 60

now we sub and find b, the y int

60 = 15(4) + b

60 = 60 + b

60 - 60 = b

0 = b

so ur equation is : y = 15x <===

how many pies must be made to make 165... so we sub 165 in for y in the equation and solve for x, the number of pies needed

y = 15x

165 = 15x

165/15 = x

11 = x <=== she would have to sell 11 pies

answer: b.36 feet
