Answer:
y = 2x + 60
Step-by-step explanation:
Use the equation for a line: y = mx + b
Where
x and y are points on the graph
and m is the slope, and can be found by finding
so the slope is 10/5 or 2, since the graph goes up by 10 and over by 5.
so plug into the equation, and you get y = 2x + b
Next, pick a point on the graph, and plug in the x and y coordinates,
for example:
(x,y) = (5,70)
so, 70 = 2(5) + b
then solve for b
60 = b
Then rewrite the equation
y = 2x + 60
Each person would get pizza.
Solution:
Total quantity of pizza =
Number of persons shared = 3
To find how much pizza would each person get:
Let us first convert improper fraction into mixed fraction.
Now divide the total quantity of pizza by the number persons shared.
Divide both numerator and denominator by 3.
Quantity of pizza each person get =
Hence each person would get pizza.
