Y =1/3x - 1 so slope = 1/3
if <span>perpendicular, slope = -3
passing thru (4,-2) then
y = mx +b
-2=-3(-2) + b
-2=6+b
-2-6 = b
so b = -8
equation:
y = -3x - 8</span>
Answer:
unit rate is similar to speed / velocity:
[<em>unit</em><em> </em><em>rate</em><em> </em><em>must</em><em> </em><em>have</em><em> </em><em>units</em><em> </em><em>including</em><em> </em><em>per</em><em> </em><em><</em><em>time</em><em>></em><em> </em>]
That would be 6 *3 - 8*0 = 18
