Question 1018651
9-x=2y;
y=(9/2)-(x/2).
Slope is -1/2
y-intercept is 9/2.
Write the equation with y isolated on one side.
----------------------------
s=450+100r; let r=an extra shift at work.
He will save $450 a year regardless plus $100*the number of extra shifts he works per year.
The slope is money gained from extra shifts worked. The S-intercept is the amount he will save regardless.
To save $1250, he has to work at least 8 extra shifts a year.
-------------------------
the domain is 0<=x<=8
The range is 450<=S<=1250.
