Answer:
Step-by-step explanation:
<u>Given points:</u>
<u>Slope is:</u>
- m = (y2 - y1)/(x2 - x1)
- m = (-5 - 1)/(8 - (-2)) = -6/10 = -3/5
- m = -3/5
<u>Use formula y = mx + b, substitute x = -2, y = 1, m = -3/5, find y-intercept b:</u>
- 1 = (-3/5)*(-2) + b
- 1 = 6/5 + b
- b = 1 - 6/5
- b = - 1/5
Correct option is B.
The first thing we must know is the following definition:
d = v * t
Where,
d: distance
v: speed
t: time
Therefore, the total distance traveled in this case is:
(5.5) * (0.5) + (1.5) * p = 13.25
Rewriting:
2.75 + 1.5p = 13.25
Clearing the value of p we have:
p = (13.25-2.75) / (1.5)
p = 7
Answer:
an equation representing this situation is:
2.75 + 1.5p = 13.25
DeAngelo's rate for the last 1.5 hours of his run is 7 miles per hour
D. 1/4 i think sorry if i’m wrong
4+1=5
-3-4=-7
-5/7 is slope
y+1=-5/7(x-4) < this is point slope form
hope this helps
