hey
OpenStudy (rawfeeds-):
@Photon336
OpenStudy (photon336):
so yeah we know that y = m(x)+b
OpenStudy (help108):
@Photon336 i need help on a question i tagged u on plezzz after u finish this one

slope = -2 = m
y = -2x+b
but we need to find b
we can do this by putting the point (8,12) into the equation.
-2(8)+b = 12 to find b
12 = -16+b

@Photon336
OpenStudy (photon336):
@RawFeeds- solve for b and show me what you get
OpenStudy (rawfeeds-):
i need help
OpenStudy (photon336):
12 = -16+b do you know how to solve for b?

no
OpenStudy (photon336):
all you do is add 16 to both sides
12+16 = b
b = 28
so it becomes this:
y = -2x+28
OpenStudy (rawfeeds-):
so thats the answer
OpenStudy (photon336):
that's what they mean by slope intercept form
OpenStudy (rawfeeds-):
ok @Photon336

ok im stuck
OpenStudy (photon336):
so we have y = -2x+28 so we are done
OpenStudy (rawfeeds-):
ok
