Suppose you were told that the company built the fence 4 hours and that they completed 1\6 mile of the fence each hour. How woul
d you use the double number line to help you find he length of the fence?
1 answer:
Answer:
Given,
Time spent in fencing = 4 hours,
Length fenced in each hour = miles.
We need to find : The length of the fence.
By using the double number line to solve this problem,
We will follow the following steps,
Step 1 : Draw two straight parallel lines, first represents time in hours second represents length in miles.
Step 2 : Make 4 tick marks in first line in which each mark represents each hour.
Step 3 : Make corresponding 4 marks in second line.
Step 4 : If first tick in second line represents 1/6 then it is obvious that last tick mark represents 4/6 or 2/3.
Hence, the length of fence is 2/3 miles.

The following equations is equivalent to the slope formula is A) y₂= m(x₂-x₁) + y₁.
<h3>What is slope?</h3>The angle of inclination of a line with respect to the horizontal is quantified. In analytical geometry, a line, ray, or line segment's slope is the proportion of the vertical to the horizontal distance between any two points ("slope equals rise over run").
<h3>What is equation?</h3>Two expressions are combined by the equal sign to form a mathematical statement known as an equation. For instance, a formula might be 3x - 5 = 16. We discover that the variable x has a value of 7 after solving this equation.
Given that,
Take a look at the formula below for the slope between two coordinate locations, m.
m =
Here, slope is
m =
Where m is the slope and y₁ and y₂ and x₁ and x₂ are coordinates of the axis.
The first step is to multiply x₂-x₁ on both sides in order to acquire y₂ on its own.
so you must add y₁ to both sides in order to get y₂ alone.
m(x₂-x₁) +y₁ = y₂.
Therefore, the following equations is equivalent to the slope formula is A) y₂ = m(x₂-x₁) + y₁.
