From any point on the graph, he counts up 2 then right 3 to end up on the line again.
From any point on the graph, he counts down 2 then left 3 to end up on the line again.
Answer:
The answer is: From any point on the graph, he counts down 2 then right 3 to end up on the line again.
Step-by-step explanation:
To count the slope of the graph from any point on the graph; He counts down 2 then right 3 to end up on the line again.
The slope of a linear graph refers to the change behaviour of its dependent variable (usually y-axis) with respect to its Independent variable (usually x-axis).
In essence;
slope, m = (y2-y1)/(x2-x1)
Consequently, From any point on the graph, he counts down 2 then right 3 to end up on the line again.

The total cost of renting a banquet hall is a function of the number of hours the hall is rented. The owner of the banquet hall charges $85 per half hour up to a maximum of 4 hours plus a $50 cleaning fee. What is the greatest value in the range for this situation?
What is the slope of the line that passes through the points (26, 7) and (-39, 12)
Answer:
It would be $390 for the 4 hours and the cleaning fees. And the slope would be -13 if you are going from 12 to 7 but would be 13 if you are going from 7 to 12...

What is the value of T in this exterior angle
Answer:
t =30
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the opposite interior angles.
t + (2t-28) = t+32
Combine like terms
3t -28 = t+32
Subtract t from each side
3t -28-t = t+32-t
2t -28 = 32
Add 28 to each side
2t-28+28 = 32+28
2t = 60
Divide by 2
2t/2 = 60/2
t =30

Which is the better buy?
A 450 g box of cereal for $4.69 or a 600 g box of cereal for $6.49?
Please show ALL of your work.
hint: convert each to a unit rate using "cost / gram", then compare each to see which is cheaper.
Answer: The first box (the 450 g box for $4.69)
===========================================================
Explanation:
To get the unit cost, we'll divide each price by the weight
The first box has a unit cost of (4.69)/450 = 0.010422 approximately which rounds to 0.01; so this unit cost is approximately $0.01 per gram or 1 cent per gram.
For the second box, its unit cost is (6.49)/600 = 0.0108167 approximately. When we round to the nearest cent, we get the same unit cost as before. Without rounding, we see that the first box has a slightly lower unit cost. Therefore box 1 is the better buy.
