Front

What is the equation of a line given a slope of 2/3 and a y-intercept of -3?

Back

y = \frac{2}{3}x - 3

Front

What does the graph of a system of equations with no solution look like?

Back

Parallel lines

Front

What is the formula for finding the slope of a line?

Back

Slope = \frac{y_2 - y_1}{x_2 - x_1}

Front

Solve the system of equations: 2x - 3y = 6 and 7x - 3y = -9. What is the solution?

Back

(-3, -4)

Front

Write the equation of the line with a slope of 1/3 and a y-intercept of -2.

Back

y = \frac{1}{3}x - 2

Front

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

Back

The y-intercept is the value of b.

Front

What does it mean if two lines are skew?

Back

Skew lines do not intersect and are not parallel.

Front

How do you determine if a system of equations has infinitely many solutions?

Back

If the equations represent the same line.

Front

What is the standard form of a linear equation?

Back

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

Front

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

Back

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