Answer:
-3x+5
Step-by-step explanation:
y2-y1/x2-x1
So the y value of the vertex of the parabola that models the data should be the left hand side of the chart; Number of $2 increases in price. So however your graph is, it should make sense.

Answer:
75 inches
Step-by-step explanation:
First, the perimeter of a rectangle is 2(length)+2(width). The length and total of the perimeter was given to us, so the equation looks like 2(48)+2(w)=246
96+2w=246 (multiply and add where you can on both sides)
2w=150 (get all of the variables on one side and the numbers on the other)
w=75 (simplify to get your final answer)
width is 75 inches. [make sure to add the units!]
