5/3 is greater improper fraction comes out to 1 2/3
(4,-3) does not pass through the graph
If you put (4, -3) into the equation you get 18
If you put (4/3, -1) into the equation you get 6
If you put (-2, -6) into the equation you get 6
For lines to be perpendicular their slopes must be negative reciprocals of one another, mathematically:
m1*m2=-1, and in this case:
-m/4=-1
-m=-4
m=4, so the slope of the perpendicular line is 4 so we have thus far:
y=4x+b, using point (-4,3) we can solve for the y-intercept, "b"
3=4(-4)+b
3=-16+b
19=b, so our line is:
y=4x+19
