Answer:
1) $63.60
2) y=8x-6
Step-by-step explanation:
1) $233.20 divided 11 hours is a hourly rate of $21.20. $21.20 multiplied by 3 hours is $63.60.
2) To find the slope you need 
. (10-2)/(2-1) is 8. The slope is 8. So you have y=8x+b. To find b just plug in a point and solve. 2=8(1)+b. B= -6. y=8x-6
No it is a straight line they are not collinear
