Answer:
Step-by-step explanation:
This is a linear graph so the equation will be in the format of y=mx+b.
b, the y-intercept, will be -3, as that is where the line crosses the y-axis.
m, the slope, is 
, calculated from the change in y over the change in x from points (-4,0) to (0,-3).
Now substitute the values in our equation:
The slope-intercept form:
We have (1, -7) and (-1, 1).
Substitute:
Therefore we have
Substitute the coordinates of the first point to the equation of line:
Answer:
11-15 Why: cause it’s beside 8 and 10
Divide 253 by 20 to get the unit rate.
We get 12.65
So our unit rate is; $12.65 per hour
6(y+x)=6y+6x
Hope this help! :)
