y=mx+b is the slope-intercept formula
"per person" represents slope which is m
the parking is like a y-intercept which is b

@KathyMae95  still there?

mehek14 · Answer

y is the total so put y=
y=
now 9 per person is 9x
so y = 9x
now you pay 3 for parking. It doesn't say 3 per parking so you just put 3
now the equation is y = 9x + 3
