Linear Equations

What is a positive slope?

• A negative slope means that as x increases, y decreases.

• A positive slope means that as x increases, y also increases. The line rises from left to right.

• A slope of zero means that y remains constant as x increases.

• A positive slope means that as x decreases, y increases.

What does it mean if a line is horizontal?

• A horizontal line has a slope of zero and indicates that the y-value does not change.

• A horizontal line has a slope of one and indicates that the x-value does not change.

• A horizontal line has a slope of negative one and indicates that the line is decreasing.

• A horizontal line has an undefined slope and indicates that the line is vertical.

What does it mean if a line is vertical?

• A vertical line has a slope of zero and indicates that the y-value does not change.

• A vertical line has an undefined slope and indicates that the x-value does not change.

• A vertical line has a positive slope and indicates that both x and y values change.

• A vertical line has a negative slope and indicates that the y-value increases as the x-value decreases.

What is a linear equation?

• A linear equation is an equation that makes a straight line when graphed. It can be written in the form y = mx + b, where m is the slope and b is the y-intercept.

• A linear equation is a polynomial equation of degree two.

• A linear equation is an equation that represents a curve on a graph.

• A linear equation is an equation that has no solutions.

If a line has a slope of 1/2, what does this mean?

• A slope of 1/2 means that for every 2 units the line moves horizontally to the right, it moves 1 unit vertically up.

• A slope of 1/2 means that for every 1 unit the line moves horizontally to the right, it moves 2 units vertically up.

• A slope of 1/2 means that the line is vertical and does not change in height.

• A slope of 1/2 means that for every 2 units the line moves vertically up, it moves 1 unit horizontally to the right.

What does the slope of a line represent?

• The slope of a line represents the rate of change of y with respect to x.

• The slope of a line indicates the length of the line segment.

• The slope of a line shows the total distance covered by the line.

• The slope of a line represents the angle of intersection with the x-axis.

What is the slope of the line that passes through the points (1, 2) and (3, 6)?

• 1

• 2

• 3

• 4

What is a negative slope?

• A negative slope means that as x increases, y decreases. The line falls from left to right.

• A negative slope means that as x increases, y increases. The line rises from left to right.

• A negative slope indicates that there is no change in y as x changes.

• A negative slope means that y is always greater than x.

What is the slope of the line represented by the equation y = 3x + 2?

• 1

• 2

• 3

• 4

What is zero slope?

• A zero slope indicates a vertical line where y changes with x.

• A zero slope indicates a horizontal line where y remains constant regardless of x.

• A zero slope indicates a diagonal line with a positive slope.

• A zero slope indicates a diagonal line with a negative slope.
