Slope and Y-Intercept

Front

What is the slope in the equation y = mx + b?

Back

The slope is represented by 'm'.

Front

Which equation represents a non-proportional relationship?

Back

y = 2x + 3 is non-proportional because it has a y-intercept.

Front

What is the y-intercept of the graph if it crosses the y-axis at 1?

Back

The y-intercept is 1.

Front

What is the y-intercept in the equation y = 2x - 5?

Back

The y-intercept is -5.

Front

What does a negative slope indicate about a linear graph?

Back

The line slopes down when reading the graph from left to right.

Front

Define slope in the context of a linear equation.

Back

Slope is the measure of the steepness of a line, calculated as the rise over run.

Front

What does the y-intercept represent in a linear equation?

Back

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

Front

How can you identify a proportional relationship from an equation?

Back

A proportional relationship has no y-intercept (b = 0) in the equation y = mx.

Front

What is the slope of the line represented by the equation y = -3x + 4?

Back

The slope is -3.

Front

If a line has a slope of 0, what does that indicate?

Back

A slope of 0 indicates a horizontal line.
