If the line is
3=-3*6+b
b=21 so
$/cap=-3(caps)+21
a) 9=-3(4)+21=-12+21=9 checks
b) 0=-3(7)+21=0 checks
c) 5=-3(5)+21=6 does not check
You can check the rest.
Suppose a line passes through the point (6 caps, $3/cap) and has a slope of -3. Which of the following points also lie along that line? Select all that apply.
a) 4 caps, $9/cap
b) 7 caps, $0/cap
c) 5 caps, $5/cap
d) 2 caps, $7/cap
e) 7 caps, $1/cap
f) 4 caps, $5/cap
My answer: a, c, e
Am I correct?
