What is m and what is x and y?
y=mx+b
Solve for b.
Then to make your eqn of a line,
jut put your m and b into y=mx+b.

x = -3?

OpenStudy (anonymous):

-3 = 0*-2 +b
What is b?

OpenStudy (anonymous):

now plug in your m and b.
y=0x -3

a.
y = -3
b.
x = -3
c.
y = -2
d.
x = -2 Its only askng for one point

OpenStudy (anonymous):

It's just y=-3 because 0 slope means horizontal slope

OpenStudy (anonymous):

@Lib Libs try to use logic first :-)

OpenStudy (anonymous):

not just guess

OpenStudy (anonymous):

I didn't guess.

Undefined slope is vertical, 0 slope is horizontal so the equation is just x= or y = depending on which situation you're dealing with

OpenStudy (anonymous):

So whenever you try to find the eqn of a line, you need "m" and "b"
You can find b if you have your point and a slope.
You can find m if you have a point and a y-intercept (if a point is (0, something)), then it's both).
