Put it in the expression y=mx+b
OpenStudy (anonymous):
B is the y-intercept and m is the slope
OpenStudy (igreen):
Take any two points on the line and plug them into the slope formula.
Let's take (0, -4) and (2, 2)
\(m = \dfrac{2+4}{2-0}\)
Simplify that
OpenStudy (anonymous):
Mind telling me where it intercepts at the y-axis?
Still Need Help?

Yes, and the y-intercept is where the line touches the y-axis.
OpenStudy (anonymous):
Yes
OpenStudy (anonymous):
What is it @sethRB26DETT
OpenStudy (anonymous):
@iGreen its 3
OpenStudy (igreen):
Yes, that's our slope.
Now what's the y-intercept?

No
OpenStudy (anonymous):
the y intercept is -4
OpenStudy (anonymous):
That is the x-intecept
OpenStudy (anonymous):
Yes!
OpenStudy (igreen):
Yep, so we have:
y = 3x - 4

Correct so now plug it in!!
OpenStudy (anonymous):
@iGreen is that my answer?
OpenStudy (igreen):
Yep
OpenStudy (anonymous):
Now we will do the slope which is rise/run.
OpenStudy (anonymous):
alright thanks

Find 2 points. Go up and then to the right that is your slope.
OpenStudy (anonymous):
@iGreen that was wrong......
OpenStudy (igreen):
That's correct..you probably typed it in wrong.
OpenStudy (anonymous):
i typed y=3x-4
OpenStudy (igreen):
Oh, that is wrong..hold on.

Oh..I took the wrong points for the slope..sorry.
Take any two points on the line and plug them into the slope formula.
Let's take (0, -4) and (1, 2)
\(m = \dfrac{2+4}{1-0}\)
Simplify that
OpenStudy (anonymous):
6
OpenStudy (igreen):
Yep, so the equation is actually:
y = 6x - 4
OpenStudy (anonymous):
okay can you help with this one to please
OpenStudy (igreen):
Okay, close this one and open a new one
