Answer:
Profit = 75
Step-by-step explanation:
Selling price of 3 oranges = 2
There are 210÷3 = 70 set of oranges
Selling price of 1 set (3 oranges) of orange = 2
Selling price of 70 set of oranges = 70 * 2 = 140
Cost of 210 oranges = 65
Profit = selling price - cost price
= 140 - 65
= 75
The slope of the line is 3/4 and the y-intercept is -1
Answer:
The slope of this line is 7/4 or 1.74 in decimal form.
m = 7/4 OR m = 1.75
Step-by-step explanation:
slope = y^2 - y^1 / x^2 - x^1
Let's pick any two points from the graph: (-1, -3) and (3, 4)
m = y^2 - y^1 / x^2 - x^1
m = 4 - (-3) / 3 - (-1)
m = 4 + 3 / 3 + 1
m = 7/4
m = 1.75
For this case we have the following equation:

Let 
We have:

By definition, given an equation of the form 
The quadratic formula, to find the solution can be written as:

In this case we have:

Substituting in the quadratic formula we have:
