First, set up the equation using the point-slope formula (y-y1)=m(x-x1).
y1=-4 x1=-3 m=-7/2
(y+4)=-7/2(x+3)
Second, distribute -7/2.
(y+4)=(-7/2)x - 21/2
Third, subtract 4 from both sides.
(y+4)=(-7/2)x - 21/2
-4 -4
______________
y=(-7/2)x - 29/2
Altogether :

For one avocado it costs $2
Answer:
x= 1, 2
Step-by-step explanation:
The quadratic formula is . Here a=1, b=-3, and c=2.
Substitute and you'll have:
Answer:
2
Step-by-step explanation:
For each change if 2 in y, there is a change of 1 in x.
The slope is 2/1 = 2
Answer: 2
