Answer:
y = 7x + 1
Step-by-step explanation:
Slope m = 7 and pass-thru point (1,8)
Start with y = mx + b. Subst. 9 for y, 7 for m and 3 for x, obtaining:
8 = 7(1) + b. Then b = 1.
The desired equation is y = 7x + 1.
He was running at a speed of 45m/s
Find the difference between the midpoint and the known endpoint by subtracting the X and Y values from each other:
X: 10 - 6 = 4
Y: 7 - 4 = 3
Now add those values to the midpoint to find the other endpoint:
X: 10 +4 = 14
Y: 7 +3 = 10
Endpoint = (14,10)
