Graphing Equations

Front

What is the order of the steps in graphing a slope-intercept equation?

Back

1. Plot the y-intercept 2. Use the slope to plot two more points 3. Connect the dots to make a line

Front

If a system of linear equations has one solution, what does this mean about the two lines?

Back

The two lines are intersecting lines.

Front

Which graph represents x=2?

Back

Graph D represents x=2.

Front

What is 'b' in the linear equation y=5x-6?

Back

b = -6

Front

What is the solution to the system of equations represented by the points (1, -1), (-1, 1), (0, -2), (2, 0)?

Back

The solution is (1, -1).

Front

What does the slope of a line represent?

Back

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

Front

What is the slope-intercept form of a linear equation?

Back

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

Front

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

Back

Set x = 0 in the equation and solve for y.

Front

What does it mean if two lines are parallel?

Back

Two lines are parallel if they have the same slope and will never intersect.

Front

What is the x-intercept of a line?

Back

The x-intercept is the point where the line crosses the x-axis (y=0).
