First find the slope of A.

Slope=(y2-y1)/(x2-x1)=(4-0)/(0--7)=4/7

For a line to be perpendicular to line A, it must have a slope that is the negative reciprocal of the slope of A. Mathematically:

m1*m2=-1 and in this case the perpendicular line will have a slope of:

4m/7=-1

4m=-7

m=-7/4

So the slope of the line perpendicular to A is -7/4

Kaya rented a limousine for prom. There was a one time charge of $100 dollars plus an hourly rate of $45. Her total cost for the

AleksAgata [21]

Hello!

Firstly, let's subtract the one time charge of $100, because we know for sure that Kaya is paying that:

347.50 - 100 = 247.50

Now, divide this by the hourly rate:

247.50 / 45 = 5.5

Kaya rented the limo for 5.5 (five and a half) hours. =)
