Slope and Graphing linear equations review

What is the equation of a line in slope-intercept form?

• y = mx + b, where m is the slope and b is the y-intercept.

• y = b + mx, where b is the slope and m is the y-intercept.

• y = mx - b, where m is the slope and b is the y-intercept.

• y = b - mx, where b is the slope and m is the y-intercept.

What is the slope of a horizontal line?

• 1

• -1

• 0

• undefined

If a line has an undefined slope, what type of line is it?

• A horizontal line.

• A vertical line.

• A diagonal line.

• A curved line.

What does it mean if the slope is negative?

• The line rises as it moves from left to right.

• The line falls as it moves from left to right.

• The line is horizontal.

• The line is vertical.

What is the slope between the points (6, 1) and (6, 2)?

• 0

• 1

• Undefined

• Infinity

What is the slope of a vertical line?

• 0

• 1

• Undefined

• Infinity

If a line has a slope of 0, what type of line is it?

• A vertical line.

• A diagonal line.

• A horizontal line.

• A curved line.

How do you calculate the slope between two points (x1, y1) and (x2, y2)?

• Slope (m) = (y2 - y1) / (x2 - x1)

• Slope (m) = (x2 - x1) / (y2 - y1)

• Slope (m) = (y1 + y2) / (x1 + x2)

• Slope (m) = (y2 + y1) / (x2 - x1)

What is the y-intercept of a line?

• The point where the line crosses the y-axis.

• The slope of the line.

• The point where the line crosses the x-axis.

• The distance from the origin to the line.

What is the x-intercept of a line?

• The point where the line crosses the x-axis.

• The point where the line crosses the y-axis.

• The slope of the line at a given point.

• The distance from the origin to the line.
