N Example 3, the points are(0,3500) and (5,1750). Write an equation that represents the distance y (in feet) remaining after x months. How much time does it take to complete the tunnel?

Step-by-step explanation:

The given points are (0, 3500) and (5, 1750).

First, we use the formula below to find the slope of the line

Which means the function is deacrasing with a ratio of 350 feet per month.

Now, we use the slope and one point to find the equation

This linear function shows that the situation started at the y-intecept (0, 3500), which means the month 0 had already 3500 feet. In other words, the total distance is 3500 feet. Now, the x-intercept will tell us the time needed to travel that distance.

Therefore, the time needed is 10 months.

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}
