Step-by-step explanation:
5/8=20/p
p=32
.............
The y intercept is 0, and the slope is 5x.
Equation: y = 5x +0.
Answer:
b=12.50p
Step-by-step explanation:
Given :
x y
0 0
2 25
4 50
6 75
8 100
10 125
To Find: Which equation can be used to determine p, the cost of b boots?
Solution :
Using point slope form Find the equation of line of the given coordinates
Let 
Let 
So, formula : 


Now we are given that cost of b boots is p
Since we are given that x axis is Number of Boots and y in price
So in the equation put x = b and y = p
So, equation : b=12.50p
Hence Option 4 is correct
Answer:
x=-2, y=3. (-2, 3).
Step-by-step explanation:
y=-x+1
y=3
----------
-x+1=3
-x=3-1
-x=2
x=-2
y=-(-2)+1
y=2+1=3
