(4x-7y)(4x+7y)
4x times 4x= 16x^2
-7y times 7y= -49y^2
Multiple 6 with 3 and 1 with 2
2/18 = 19
The standard formula of a point-slope equation is (y-y1) = m(x-x1). So, we would arrange the final equation in this way as much as possible. Let y be the total amount her receives and x be the number of miles. That would be
y = 200 + 20x
y = 20 (10 + x)
That would be the equation. If he finishes the walk,
y = 20 (10+5)
y = $300
he would receive a total of $300.
