oops i meant i am checking my equation to see if it is 0
OpenStudy (anonymous):
ok i got 0
OpenStudy (anonymous):
what did u get?
OpenStudy (anonymous):
m = (-6-(-3))/(-6-(-4))
m = -3/-2
m = 3/2
(y-(-6)) = 3/2(x-(-6))
y+6 = 3/2x + 18/2
y = 3/2x + 3
-
m = (3-(6))/(0-2)
m = -3/-2
m = 3/2
(y-3) = 3/2(x-0)
y-3 = 3/2x
y = 3/2x + 3
-
3/2x+3 = 3/2x+3
so x = x
so any value of x will work
so D. Infinitely many
