Find the slope of the line that contains the points named. X(2, -1), Y(0, 4)
Do you know the formula for the slope of a line?
no
slope = (Y - Ysub1)/(X - Xsub1)
so its the difference of the Y coordinates divided by the difference of the X coordinates
Ill set it up the Y coordinates and you do X (4 - (-1))/X - X
Do you see what I did? You know the difference between the X and Y coordinates correct? I don't know why they named the points X and Y because that will just confuse someone who is not familiar with the material.
alright so we have point P(X, Y) and point M(X, Y). We want to subtract one point from the other. It doesn't matter which. So replace the coordinates of P(2, -1) and M(0, 4). Do you see the Y coordinates and x coordinates now?
yes i see so it would be 5/2 ?
you forgot one part. take a look at the x coordinates again
-5/2
yeah, very good
thank you so much
