Question 687285: I don't know how to work out and graph the following:
-contains the point (-3,-8) and is perpendicular to y = -3/4x + 6
I tried this but I tried graphing it and it didn't work out:
y-(-8)=4/3(x-(-3)) which converts to y+8=4/3x+12/3 or 4 (I think) which then converts to y=4/3x-4 (I think)
P.S. -3/4 means negative three over four. And 4/3 means four over three. Like, in fraction form.
