Answer:
12.5r
Step-by-step explanation:
You just add all the numbers together and then add the r at the end it’s pretty easy when you know that
(-4,-4)(1,3)
slope = (3 - (-4) / (1 - (-4)
slope = (3 + 4) / (1 + 4) = 7/5
y - y1 = m(x - x1)...using (-4,-4)
slope(m) = 7/5
y - (-4) = 7/5(x - (-4) =
y + 4 = 7/5(x + 4) <==here is one
y - y1 = m(x - x1)..using (1,3)
slope = 7/5
y - 3 = 7/5(x - 1) <== here is the other one
Is there a rate of acceleration? If not then by using the formula time = distance/speed you get 160/30. Which equals 5.333, so I would go with B.
