Front

Define the gradient of a straight line.

Back

The gradient (or slope) of a straight line is a measure of its steepness, calculated as the change in y divided by the change in x (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, indicating the value of y when x is 0.

Front

What is the significance of a gradient of 0 in a linear equation?

Back

A gradient of 0 indicates a horizontal line, meaning the y-value remains constant regardless of the x-value.

Front

What does a negative gradient indicate about a line?

Back

A negative gradient indicates that the line slopes downwards from left to right.
