Final Exam Review Part 1 ( Staar interim Review )

Front

What is a function?

Back

A function is a relation between a set of inputs and a set of possible outputs where each input is related to exactly one output.

Front

Which set of values represents a function?

Back

(6,-5) (7,-3) (8,-1) (9,1) because each x-value is unique.

Front

What does the graph of y ≤ -4x look like?

Back

The graph is a straight line with a slope of -4, shaded below the line.

Front

What are the slopes of parallel lines?

Back

The slopes of parallel lines are the same.

Front

What is the ordered pair that satisfies both equations x and y?

Back

(4, 1) is the ordered pair that satisfies both equations.

Front

How do you find the slope between two points?

Back

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

Front

What is the slope of the line represented by the points (1, 2) and (4, 5)?

Back

The slope is (5 - 2) / (4 - 1) = 3/3 = 1.

Front

What is the definition of a linear equation?

Back

A linear equation is an equation that makes a straight line when graphed.

Front

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

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 two lines to be perpendicular?

Back

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