What does the slope of a line represent?

Back

The slope of a line represents the rate of change of y with respect to x. It indicates how steep the line is and the direction it goes (positive slope means it rises, negative slope means it falls).

Front

Back

The slope is 2 and the y-intercept is -3. This means for every 1 unit increase in x, y increases by 2 units.

How do you find the slope from two points (x1, y1) and (x2, y2)?

What is a zero of a function?

Back

A zero of a function is a value of x that makes the function equal to zero. It represents the x-coordinate of the point where the graph intersects the x-axis.

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

Back

The y-intercept represents the value of y when x is 0. It is the point where the line crosses the y-axis.

How can you determine the x-intercept from a linear equation?

Back

To find the x-intercept, set y to 0 in the equation and solve for x.
