Perpendicular slope: 3
y + 7 = 3(x + 3)
y + 7 = 3x + 9
y = 3x + 2
For this case we have the following system of equations:

Equating both equations we have:

We must find the solutions, for this we factor. We look for two numbers that, when multiplied, result in 4 and when added, result in 5. These numbers are 4 and 1:

Then, the factorized equation is of the form:

Thus, the solutions are:

We look for solutions for the variable "y":

Thus, the system solutions are given by:

At 1/8 of a gallon you can mow 2 1/4 so for 1 gallon just multiply 2 1/4 by 8
16+2 is 18
Answer is <span>B.
Quadrant II </span>
So 0.16 is also equal to 16/100 so, just draw 100 squares and shade 16 of em'
