Hey there! :D
Find the slope first. (0,7) (1,8)
m= (y2-y1)/(x2-x1)
m= (8-7)/(1-0)
m= 1/1
m=1
Now, use those points in point slope form. (0,7) as the point.
y-y1= m(x-x1)
y-7= 1(x-0)
y-7= 1x-0
Add 7 to the other side.
y= 1x+7 <== that is in y=mx+b form
or y= x+7
I hope this helps!

As time time starts at zero, he is at home. As time goes on, he travels to a given location, which is why his distance increases. He then stays there for a while which is why the time continues to go on but his distance doesn't change. He then rides home quickly.
87 is the mean.
To find the mean, you must
- add all of the numbers
- divide by the amount of numbers given
In this case, you would want to do (86 + 80 + 95)/3. This would give you an answer of 87.
Answer:
Step-by-step explanation:
<u>Given equation</u>
<u>Answer choices</u>
A. The equation represents a proportional relationship.
- TRUE, it is in the form of y = kx
B. The unit rate of change of y with respect to x is 8.5
- TRUE, y = mx + b, the slope m = 8.5 is the rate of change
C. The slope of the line is 2/17
D. A change of 17 units in x results in a change of 2 units in y.
- False, a change of x = 17 results in 17*8.5 = 144.5 units in y
E. A change of 4 units in x results in a change of 34 units in y.
