# Math: slope problem

posted by .

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?

• Math: slope problem -

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.
