Front

What are the x-intercepts of the quadratic function f(x) if they are at (-3,0) and (5,0)?

Back

(-3,0) and (5,0)

Front

If lines L and M are perpendicular and the slope of line M is -\frac{4}{3}, what is the slope of line L?

Back

\frac{3}{4}

Front

What is the slope of the line passing through points A and B if the slope is \frac{1}{2}?

Front

What is the slope of a line parallel to the line whose equation is y = 5x + 4?

Back

5

Front

Define the term 'slope' in the context of a linear equation.

Back

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

Front

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

Back

Slope = \frac{y2 - y1}{x2 - x1}

Front

What does it mean for two lines to be perpendicular?

Back

Two lines are perpendicular if the product of their slopes is -1.

Front

What is the y-intercept of a line?

Back

The y-intercept is the point where the line crosses the y-axis, represented as (0, b) in the equation y = mx + b.

Front

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

Back

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