Which line is perpendicular to a line that has a slope of -1/3?

Hello from MrBillDoesMath!

line EF

Discussion:  Two lines, L1 and L2, with slopes m1 and m2 are perpendicular if

m1 * m2 = -1. In our case m1 = -1/3 so the slope of the perpendicular line is 3.

( 3 * (-1/3) = -1).  The line with slope 3 is rising as x gets larger.  The only line shown fitting this is line EF.  Note that line AB is "falling" as x increases so it can not possibly be the answer.

step-by-step explanation: the answer is 27. first multiply .32 by 25 which equals 8. then add 8 to 25 which gives you 33. then you subtract that from 6 since she gave 6 to her brother.

,, add !

y = i/2 xtnop + (3i/2 tnop+ 1)
