Answer:
The slope is 
.
Step-by-step explanation:
Choose 2 points on the graph.
(7,3) and (2,2)
Use slope formula: 
=
The slope is .
Step-by-step explanation:
1. 10s2 + 10s2 - 13st = 20s2-13st
2. 13st + - 2st - t2 = 11st - t2
3. x2+ x2 + x3= 2x2 + x3
4. 6 x - 6 x + 2=X+2
5. 24x - 3s - 4t=24x - 3s - 4t
6. 86 + 86x - 1=85+86x
7. 4x + 3x - 2 =7x - 2
8. 7s - 4s + 3s =6s
9. 12 +11x - 10 x = 12+x
10. 12x + 24 x - 3 x - 4 =33x -4
11. 16t + 8t - 12t =12t
12. 17g + 19g - 2g +g =35g
13. 16 + 16 -16 + 16x =16+16x
14. 4s - 3s + 3s =4s
15. 12t - 11t + t =2t
Answer:
The square root of pi is 1.7724
Desmond's times are proportional. for every 2 laps he takes 146
146 / 2 = 73
292 / 4 = 73
584 / 8 = 73
Maria's time are not proportional
150 / 2 = 75
320 / 4 = 80
580 / 6 = 96.67
Number 3 because there is one output(y value) for one input (x value)
