Front

What is the definition of a zero slope in a graph?

Back

A zero slope indicates that the line is horizontal, meaning there is no change in the y-value as the x-value changes.

Front

Calculate (15 + 18) - 5.

Back

28

Front

What is the slope-intercept form of a linear equation?

Back

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

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as the x-value increases, the y-value decreases.

Front

What is the definition of an undefined slope?

Back

An undefined slope occurs in a vertical line where the x-value does not change, leading to division by zero.

Front

Solve for d in the equation d / t = r.

Back

d = rt.

Front

What is the graphical representation of y = -x + 2?

Back

A straight line with a negative slope that crosses the y-axis at (0, 2).

Front

How do you determine the slope of a line given two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What is the y-intercept of the line y = 3x + 4?

Back

The y-intercept is 4, which is the point where the line crosses the y-axis.

Front

What does it mean for a line to have a positive slope?

Back

A positive slope indicates that as the x-value increases, the y-value also increases.
