Semester 1 Final Exam Review

Front

What is the definition of an undefined slope?

Back

An undefined slope occurs when a line is vertical, meaning it has no defined rise over run, as the change in x is zero.

Front

Back

x = -5

Front

What does the domain of a graph represent?

Back

The domain of a graph represents all the possible x-values that can be input into the function.

Front

What is the domain of the graph if it is defined as -4 ≤ x ≤ 3?

Back

The domain includes all x-values from -4 to 3, inclusive.

Front

What is the slope-intercept form of a linear equation?

Back

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

Front

How do you find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

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

Front

What is the significance of the point (-4, 3) in the equation y - 3 = 2(x + 4)?

Back

The point (-4, 3) lies on the line represented by the equation, confirming that it satisfies the equation.

Front

What does it mean if an equation has no solution?

Back

An equation has no solution when there are no values for the variable that can satisfy the equation, often resulting in a contradiction.

Front

What is a positive slope?

Back

A positive slope indicates that as x increases, y also increases, resulting in an upward slant from left to right.

Front

What is a negative slope?

Back

A negative slope indicates that as x increases, y decreases, resulting in a downward slant from left to right.
