Revolt · Accepted Answer

the line intersects the y axis at (0,12)

Question 2

Which did you include in your answer?

Revolt · Accepted Answer

The y-intercept is the y-coordinate of the point at which the line intersects the y-axis.; The line intersects the y-axis at (0, 12).; The y-intercept in slope-intercept form is b, which is 12 in the given situation.; The y-intercept represents the initial value, which in this case is $12.

Question 8

The instructor had saved $3,500 and rents an apartment for $275 monthly. He believes the point (6, 1850) would be on the equation of the line. Is he correct? Explain how to check if a point is on a line.

Revolt · Accepted Answer

First, write the equation for the line in slopeintercept form: y 275x 3500, where 275 is the monthly rent and 3500 is the initial savings. To check if the point (6, 1850) is on the line, substitute x 6 and y 1850 into the equation. 1850 275(6) 3500 1850 1650 3500 1850 1850 Since the equation is true, the instructor is correct; the point is on the line.

Question 9

y-intercept = Slope = Linear equation =

Revolt · Accepted Answer

3000; Selection 1: 3000; Selection 2: –275; Selection 3: y = -275x + 3000

Question 10

Which did you include in your answer?

Revolt · Accepted Answer

Use from (0, 12).; 8 up and 1 to the right to (1, 20); Draw a line through the points (0, 12), (1, 20).; Verify the equation by testing an additional point.
