Front

What is the x-intercept of a line?

Back

The x-intercept is the point where the line crosses the x-axis, represented as (x, 0).

Front

How do you find the value of x in an equation?

Back

To find the value of x, isolate x on one side of the equation using algebraic operations.

Front

What does the equation I = prt represent?

Back

This equation represents the relationship between Interest (I), Principal (p), Rate (r), and Time (t).

Front

How do you solve for r in the equation I = prt?

Back

Rearranging the equation gives r = I / (pt).

Front

What is the equation of a vertical line?

Back

The equation of a vertical line is in the form x = a, where 'a' is a constant.

Front

What is the equation of a horizontal line?

Back

The equation of a horizontal line is in the form y = b, where 'b' is a constant.

Front

How do you determine the slope of a line from two points?

Back

The slope (m) is calculated using the formula m = (y2 - y1) / (x2 - x1).

Front

What is the formula for the slope-intercept form of a line?

Back

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

Front

What does it mean for a line to be parallel?

Back

Two lines are parallel if they have the same slope and will never intersect.

Front

What does it mean for a line to be perpendicular?

Back

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