Front

What is the equation of a vertical line that passes through the point (9, 13)?

Back

x = 9

Front

Solve for y: 4x + 2y = 16

Back

y = -2x + 8

Front

What does it mean if a system of equations has no solution?

Back

The lines are parallel and never intersect.

Front

What is the y-intercept of the line represented by the equation y = -2x + 8?

Back

The y-intercept is 8.

Front

What is the horizontal asymptote of the function f(x) = 2x/(x+1)?

Back

y = 2

Front

Define slope in the context of a linear equation.

Back

Slope is the ratio of the rise (change in y) to the run (change in x) between two points on a line.

Front

What is the standard form of a linear equation?

Back

Ax + By = C, where A, B, and C are integers.

Front

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

Back

Set y = 0 and solve for x.

Front

What does it mean for two lines to be perpendicular?

Back

Their slopes are negative reciprocals of each other.

Front

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

Back

y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point on the line.
