Answer:
Store 1 has the better deal.
Explanation:
If you divide the amount the prices by the amount of paper towel roll, you would see store 1 has the better deal.
3.60 divided by 12 = 0.30
3.50 divided by 10 = 0.35
As you can see, store 1 is less expensive than store 2. Therefore, store 1 is the better deal.
Answer:
y = -3x - 1
Step-by-step explanation:
1) Find the slope of the line


Slope is -3
2) Plug the slope into a y-intercept form.
y = mx +b
y = -3x + b
3) Find b (which is the y-intercept) by plugging in any coordinates for the x and y.
y = -3x + b
I would like to plug in (0, -1) into the equation.
(-1) = -3(0) + b
-1 = b
4) Plug in the b into the equation.
y = -3x +b
y = -3x -1
