Graphing Using Intercepts

Front

Which ordered pair could represent a y-intercept on a graph?

Back

(0, 4) - The y-intercept occurs where x = 0.

Front

What's the definition of x-intercept?

Back

Where the graph crosses the x-axis.

Front

What is the x-intercept shown on the graph?

Back

(-2, 0) - The point where the graph crosses the x-axis.

Front

The point where the line crosses the y-axis is called the:

Back

y-intercept.

Front

What is the x-intercept of the line?

Back

(-1, 0) - The point where the graph crosses the x-axis.

Front

What is the general form of a linear equation?

Back

y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you find the y-intercept from a linear equation?

Back

Set x = 0 and solve for y.

Front

How do you find the x-intercept from a linear equation?

Back

Set y = 0 and solve for x.

Front

What does the slope of a line represent?

Back

The rate of change of y with respect to x.

Front

What is the slope of the line represented by the equation y = 2x + 3?

Back

2 - The coefficient of x represents the slope.
