Given that Joseph earns $15 for every lawn he mows.
so if he mows lown 1 time then his earning = $15
if he mows lown 2 time then his earning = $15*2= $30
if he mows lown 3 time then his earning = $15*3= $45
if he mows lown 4 time then his earning = $15*4= $60
if he mows lown 5 time then his earning = $15*5= $75
So the required table will be:
From the table we can see that Joseph's earning increases by $15 each time so we can say that YES, the amount of money he earns proportional to the number of lawns he mows.
Vertex form for a parabola with vertex (p,q) is
We have (p,q)=(-4,5) and another point (-3,2) so we can solve for <em>a:</em>
Putting it together,
Answer:
We could multiply that out if we like but I won't bother.
