Front

Which graph has a zero (0) slope?

Back

A graph with a zero slope is a horizontal line, indicating that there is no change in the y-value as the x-value changes.

Front

6(2x - 5) = 42. Solve for x.

Back

x = 6

Front

Slope is ________.

Back

Slope is a measure of the steepness of a line, which can be positive, negative, zero, or undefined.

Front

4x = 76. Solve for x.

Back

x = 19

Front

Solve for x: 3x + 9 = x - 5.

Back

x = -7

Front

What does a positive slope indicate?

Back

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

Front

What does a negative slope indicate?

Back

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

Front

What is the formula for calculating slope?

Back

Slope (m) = (y2 - y1) / (x2 - x1) where (x1, y1) and (x2, y2) are two points on the line.

Front

What is an undefined slope?

Back

An undefined slope occurs in a vertical line where the change in x is zero, leading to division by zero.

Front

What is the y-intercept?

Back

The y-intercept is the point where a line crosses the y-axis, represented as (0, b) in the equation y = mx + b.
