"time for you to learn slope intercept"
y=mx+5
y=mx+b
Oh ok

y=mx+5
"Slope intercept is when you use this formula y=mx+b. Now I will teach you how to solve this for the slope"

Oh! that's so cool

y=mx+b
y=mx+b
y=2x+5
Slope
Now the y-intercept would be 5 because any time X equals 0 that makes the Y-intercept

So now the equation would look like this, but now we have to find the slope by kinda finding what the pattern is between the numbers

Now you have to do change in Y over change in X that is when you put y over x like a fraction. For example look

That also means that the equation would look like this now that you have found the slope.

Slope
As you can see it's 2 over 1 over and over again which is constant. That means the slope is 2 it also means that this chart is proportional.
