Hey there! :)
Answer:
C. $8/hour.
Step-by-step explanation:
Find the rate of change, or slope using rise/run.
Rise = y-value
Run = x-value
Therefore:
Take a point from the graph. (2, 16) will be used in this instance:
16/2 = 8.
Therefore, the rate of change is $8/hour.
Let y represent Tim's age and let x represent Chris's age.
y=3x
y=x+14
Set the two equations equal to each other:
3x=x+14
Subtract the x from the one side to get it on the other side.
2x=14
Divide by 2 on both sides
14/2=7
x=7
Plug it back in and see if it works:
y=3(7)=21
Other equation:
7+14=21
x=7
y=21
Answer:
Point A, B, and C are collinear points.
Step-by-step explanation:
When points lie on one line, meaning all of the points are on the same line --> this is known as collinear points.
I think it might be -38, not 100% though.
If the y-intercept is at -69, meaning the point is (0, -69), thus x = 0, y = -69
