Question 1

Find the slope of the line that passes through the points (-4, -1) and (-4, 8).

Accepted Answer

The line is vertical because both points have the same x-coordinate, so the slope is undefined.

Question 2

Find the slope of the line that passes through the points (-1, 6) and (-9, 6).

Accepted Answer

The slope of a line is calculated as the change in y divided by the change in x. Since both points have the same y-coordinate (6), the change in y is 0, resulting in a slope of 0.

Question 5

Find the slope of the line whose equation is given by x = 10.

Accepted Answer

The equation x = 10 represents a vertical line, and vertical lines have an undefined slope.

Question 6

Find the slope of the line whose equation is given by y = 6.

Accepted Answer

The equation y = 6 represents a horizontal line, and the slope of a horizontal line is always 0.

Question 7

Find the x- and y-intercepts of the line whose equation is 8x + 5y = 40.

Accepted Answer

To find the x-intercept, set y = 0 and solve for x:8x + 5(0) = 408x = 40x = 5So the x-intercept is (5, 0).To find the y-intercept, set x = 0 and solve for y:8(0) + 5y = 405y = 40y = 8So the y-intercept is (0, 8).

Question 8

Find the x- and y-intercepts of the line whose equation is 2x - 5y = 20.

Accepted Answer

To find the x-intercept, set y = 0 and solve for x: 2x = 20, so x = 10. To find the y-intercept, set x = 0 and solve for y: -5y = 20, so y = -4.

Question 9

Find the x- and y-intercept of the line whose equation is y + 6 = -18.

Accepted Answer

The equation y + 6 = -18 simplifies to y = -24. This is a horizontal line, so it has no x-intercept and a y-intercept at (0, -24).

Question 10

Write the equation of the line given the slope m = -19 and y-intercept (0, 10).

Accepted Answer

The equation of a line in slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept. Given m = -19 and y-intercept (0, 10), the equation is y = -19x + 10.

Question 11
