X/2 + 5 = -10
x/2 = -10 - 5
x/2 = -15
x = -15(2)
x = -30

Answer:
No, they are not equivalent
Step-by-step explanation:
4 miles in 4 hrs.....4/4 =1...thats 1 mile per hr
for 2 hrs.....at 1 mile per hr = 2 miles <==
First, find the gradient/slope:
Use slope formula:
m=(y2-y1)/(x2-x1)
=(11-5)/(3-1)
=6/2
=3
Then use the line equation formula:
y=mx+c
You can substitute (1,5) if you like, also must substitute the slope as well!
5=3x1+c
c=2
Then find the full equation, which gives you the answer:
y=3x+2
