What is the slope of two perpendicular lines?

Back

The slope of two perpendicular lines is opposite reciprocals.

Front

Which equation represents a line with a slope of 2 and a y-intercept of 3?

Back

y = 2x + 3

Front

How do you find the x-intercept of the equation y = 3x + 18?

Back

Set y to 0 and solve for x: 0 = 3x + 18, x = -6.

Front

What is the domain of the function defined by -3 < x ≤ 3?

Back

The domain is the set of all x-values that satisfy the inequality -3 < x ≤ 3.

Front

What is the y-intercept of the equation y = -3x + 7?

Back

The y-intercept is 7.

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they have the same slope.

Front

How do you determine the slope from two points (x1, y1) and (x2, y2)?

Back

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

Front

What is the standard form of a linear equation?

Back

The standard form is Ax + By = C, where A, B, and C are integers.

Front

What is the difference between the domain and range of a function?

Back

The domain is the set of all possible input values (x), while the range is the set of all possible output values (y).

Front

How do you convert the slope-intercept form to standard form?

Back

Rearrange y = mx + b to Ax + By = C.
