(Points : 5)

y = –2x + 12



y = 2x – 12












Question 6.6.
Olayinka is participating in a bowl-a-thon to raise money for the local hospital. A sponsor will pay Olayinka $2 plus $0.10 per pin, x, that she knocks down. Which equation should Olayinka use to find the total amount of money she raised?


(Points : 5)

B = (2 – 0.10)x



B = 2x + 0.10



B = 0.10x + 2



B = (0.10 + 2)x

Answer 1

`8x+4y=48 \\ -8x-8x \\ 4y=-8x+48 \\ /4 /4 \\ y=-2x+12`

B=0.10x + 2

Answer 2

Slope - intercept form: y = mx + b

8x + 4y = 48
8x - 8x + 4y = 48 - 8x
4y = -8x + 48
4 4
y = -2x + 12

Answer: y = -2x + 12

First you subtract 8x on both sides to get 4y alone giving you 4y = -8x + 48. Then you divide by 4 on both sides to get y alone which leaves you with y = -2x + 12

Question 6.6

Answer: B = 0.10x + 2
