Answer:
Slope -1
Intercept 3
Step-by-step explanation:
We have been given that a pound of fertilizer covers 42 square feet lawn and we are asked to find amount of fertilizer to cover lawn which measures 6019.3 square feet.
To find the amount of fertilizer needed to cover the lawn we will divide the area of lawn by area covered by one pound of fertilizer.
Therefore, the amount of fertilizer that Vivian needs to buy would be 143.3 pounds.
6 out of 9 bottles were used, therefore equal to 6/9 which as a percentage (just divide 6/9 on a calculator and multiply by 100 to get a percentage) you get 66 and 2/3%
You would start by subtracting 5-7=2 which would make the equation
3x=x-2 then subtract x from both sides to get 2x=-2 then you would divide both sides by -2 so x=1
