Front

Does the table represent a proportional relationship?

Back

No, a proportional relationship means that the ratio between the two variables is constant. If the ratios are not constant, it is not proportional.

What is the y-intercept?

Back

The y-intercept is the point where a line crosses the y-axis. In the context of a linear equation, it is the value of y when x is 0.

Front

Which graph matches the table?

Back

To determine which graph matches a table, look for the graph that has points corresponding to the values in the table.

Is this equation proportional or non-proportional?

Back

An equation is proportional if it can be expressed in the form y = kx, where k is a constant. If it cannot, it is non-proportional.

What is the y-intercept?

Back

The y-intercept is the value of y when x is 0. For example, in the equation y = mx + b, b represents the y-intercept.

What does it mean if a graph is linear?

Back

A linear graph represents a constant rate of change and can be described by a linear equation of the form y = mx + b.

Front

How do you find the slope of a line?

Back

The slope of a line is found by taking the difference in y-values divided by the difference in x-values between two points on the line.

What is the formula for slope?

Back

The formula for slope (m) is m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are two points on the line.
