Austin pays $2 per day for high speed internet. The equation y = 2x relates his internet charges (y) to the number of days (x) h
1 answer:
Answer:
Option C. 2
Step-by-step explanation:
Let
x ----> the number of days
y ----> the internet charges in dollars
we have
This is a proportional relationship between the variables x and y
The slope of the linear function is equal to the constant of proportionality k
The unit rate is the same that the slope
so
The unit rate is $2 per day
therefore
The unit rate in the equation is 2

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.
