Identifying Slope and Y-Intercept

Front

What is the y-intercept in the equation y = mx + b?

Back

The y-intercept is the value of y when x = 0, represented by b in the equation.

What does the slope represent in a linear equation?

Back

The slope represents the rate of change of y with respect to x.

Front

How can you determine if a slope is positive or negative?

Back

If the line rises from left to right, the slope is positive; if it falls, the slope is negative.
