The formula of a slope:

We have the points (look at the picture) (0, 1) and (-2, -2). Substitute:

Unit price is $0.81 per bag
Answer:

Step-by-step explanation:
The equation of a horizontal parabola in the standard form:

(h, k) - vertex
if a > 0, then open right
if a < 0, then open left
We have the vertrex (-1, -3) and the parabola is open left (a < 0).
Therefore the equation of a given parabola could be:

Answer:
1/2
Step-by-step explanation:
remember that the formula for the slope of a line is

where m is the slope, and the x and y variables are the x-y coordinates of two points. Choose two points on the line:
Point 1 : (-1,3) and Point 2 : (1,4)
Plug in your values:


So the slope of this line is 1/2 !
