Parts of new orleans is currently below sea level and continues to sink each year. nasa images shows that one part of the city is currently 6 feet (72 inches) below sea level. each year it continues to sink 2 more inches. write an expression to describe the depth of new orleans after any given year.

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
