9/3 or 3
slope is rise over run. or x over y.
look at your Y points... 1, 10, 19, 28, 37. They go up 9 each time, right? 1 + 9 = 10 + 9 = 19...etc.
Now, look at your X points... 0, 3, 6, 9, 12. They go up 3 each time, right? 0 + 3 = 3 + 3 = 6...etc.
Since you go up 9 for the y axis and 3 for the x axis...
9/3
Slope= Ya-Yb/Xa-Xb
Slope= 5+3/2+3
Slope=8/5
Equation: y-ya=slope(x-xa)
Equation: y-5=8/5(x+3)
Then D is the correct answer
Answer:
7
Step-by-step explanation:
7x4=28
6x4=24
So it cant be 6 or anything less
the graph is shifter down 3 units.
It would take her about 2.5 hours
