x+y=6 and 20x+30y=140 can be used to determine the number of each type of lawn mowed by Sarah.
Step-by-step explanation:
Given, 
Charges for cutting small lawns =$20
Charges for cutting large lawns = $30
Total yards mowed = 6
Total amount earned = $140 
According to given statement; 
x+y=6    Eqn 1
20x+30y=140    Eqn 2
x+y=6 and 20x+30y=140 can be used to determine the number of each type of lawn mowed by Sarah.

Answer:
The answer is A) y+4 =3(x+3)
Step-by-step explanation:
The slope is the rate of change, which you can see from the graph is m = 3/1 = 3.
Your options are given in point-slope form:
y-y1=m(x-x1)
Pick a point from the graph. I used;
(-3, -4). Now plug this into your point slope form equation.
y-(-4) = 3(x-(-3))
y+4=3(x+3)
