Answer:
No
Steps- two rang values exist for domain value -2
1) 50*50, our 2500
2) 1500
3)1500
4) 900
just multiply t the number of people by the amount each pays
<span>y = -1/2x +2 1/2</span>
General equation;
y = mx + c
Calculating the slope;
Change in y/ (change in x) = gradient m
(2-1)/(1-3) = - 1/2
Replacing m gives;
y= -1/2x + c
Calculating the value of c
take point (1,2) above and replace y with 2 and x with 1
2=-1/2 *1 +c
c = 2 1/2
Equation then is
y = -1/2x +2 1/2
-- point (1, -2)
-- point (10, 25)
