Use the chart below to answer the questions: country population (1997 estimate) area (square km) u. s. 272,648,000 9,364,520 denmark 5,248,000 42,077 egypt 5,784,000 1,759,540 which of these countries has the greatest population density? which has the least? provide an explanation and proof for your answer to receive full credit.

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

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.

step-by-step explanation:

your answer is a
