Front

What is the equation of the line with a slope of -3 and a y-intercept of -3?

Back

y = -3x - 3

Front

What do the slopes of parallel lines have in common?

Back

The slopes of parallel lines are the same.

Front

Write an equation of a line that passes through the point (5,-1) and is parallel to the line y = (-3/5)x - 3.

Back

y = (-3/5)x + 2

Front

Define slope in the context of a linear equation.

Back

Slope is the measure of the steepness of a line, calculated as the rise over run.

Front

What is the slope of a line that is perpendicular to a line with a slope of -2?

Back

The slope of a line perpendicular to a line with slope -2 is 1/2 (the opposite reciprocal).

Front

How do you find the y-intercept of a line given its equation in standard form?

Back

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

Front

What is the formula for the slope between two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1)
