Front

What is the equation of a vertical line that passes through the point (-4, 7)?

Back

x = -4

Front

What is the equation of a horizontal line that passes through the point (3, -6)?

Back

y = -6

Front

How do you find the zero of the function f(x) = -4x + 12?

Back

Set f(x) to 0: -4x + 12 = 0, solve for x: x = 3.

Front

Back

The y-intercept is 2.

Front

What is the value of p if p = 12?

Back

p = 12.

Front

What does it mean for a line to be vertical?

Back

A vertical line has an undefined slope and is represented by an equation of the form x = a.

Front

What does it mean for a line to be horizontal?

Back

A horizontal line has a slope of 0 and is represented by an equation of the form y = b.

Front

How do you determine the slope of a line from its equation in slope-intercept form?

Back

The slope is the coefficient of x in the equation y = mx + b.

Front

Back

The slope is 2.

Front

What is the significance of the y-intercept in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, represented by the value of b in y = mx + b.
