Answer:
y=0.5x+8
Step-by-step explanation:
Use the formula for the equation of a line y=mx+c where m is the slope and c is a number.
To find the slope, take two points (x₁,y₁) (x₂,y₂) and put them into the slope equation m=(y₂-y₁)/(x₂-x₁):
We can take two points from the graph: (2,9) (4,10)
m=(y₂-y₁)/(x₂-x₁)
m=(10-9)/(4-2)
m=1/2 or 0.5
Now sub this value in for m and our formula looks like this:
y=0.5x+c
To find the value of c, sub in one of the points, eg. (4,10)
y=0.5x+c
10=0.5(4)+c
10=2+c
c=8
So now that we now m and c, our equation is complete :D
y=0.5x+8
Step-by-step explanation:
115 = 5x + 15
115 - 15 = 5x
100 = 5x
20 = x

Answer:
Varying
Step-by-step explanation:
The reason why the rate of change is varying is because the dots on the graph do not connect to make a straight line when you draw a line through the dots. When the dots connect via a straight line, it is also known as a proportional relation. A straight line would be a constant change.
Answer:
B. 
Step-by-step explanation:
The y-intercept is given to us, which is ![\displaystyle [0, 7],](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5B0%2C%207%5D%2C)
and Parallel Lines have SIMILAR <em>RATE </em><em>OF CHANGES</em><em> </em>[<em>SLOPES</em>],<em> </em>so −2 remains the way it is.
