James is participating in a 5-mile walk to raise money for a charity. he has received $200 in fixed pledges and raises $20 extra
Firlakuza [10]
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.
