...

Do you know the slope-intercept form of the equation of a line?
\(y = mx + b\)

yes i recognize that

110

ok

yes i can

One point can be the one that includes y = 110.

(10,110) ?

see i was going to say 0 but i thought it wouldn't count since 0 is the orgin

but it makes since since (0,110) = 110

my next one is (10,90)

also i just realized that 10,110 is not on the line anyway , lal

exactly ^

ok
now whet?

like x^1 - x^2
y^1 - y^2

oops i was backwords

The order does not matter, as long as you do both subtractions int he same order.

|dw:1434399014025:dw|

-20/10 is what i got

Now we need to do the subtractions in the numerator and denominator.

|dw:1434399177385:dw|

|dw:1434399221808:dw|

am i correct? @mathstudent55

|dw:1434399234449:dw|

:D

You have a fraction. A fraction means division.

i know but i thought you said subtract

|dw:1434399290651:dw|

|dw:1434399386993:dw|

You subtract the y's and you subtract the x's. Then you divide one subtraction by the other one.

Yes. The slope is -2.
That goes in the m of the slope-intercept equation.

y=-2x+110 :D

Correct.

Notice that if we used the points in the other order, the slope would still be the same:
