Final Exam Review

Front

Solve for x: |2x - 1| + 4 = 8

Back

x = 2.5 and x = -1.5

Front

Find the distance: What is the distance between two points (3, 4) and (7, 1)?

Back

Distance = 7.8

Front

What type of correlation is shown in a plot where as one variable increases, the other also increases?

Back

Positive correlation

Front

As the age of the car increases, its value decreases. What type of relationship is this?

Back

Negative correlation

Front

Identify the system of inequalities: y ≥ -x - 1 and y < x + 4

Back

y > -x - 1 and y ≥ x + 4

Front

What is the definition of absolute value?

Back

The absolute value of a number is its distance from zero on the number line, regardless of direction.

Front

What is a scatterplot?

Back

A scatterplot is a graph that shows the relationship between two quantitative variables.

Front

What does it mean if a scatterplot shows no correlation?

Back

It means there is no discernible relationship between the two variables.

Front

How do you find the slope of a line given two points?

Back

Slope (m) = (y2 - y1) / (x2 - x1) for points (x1, y1) and (x2, y2).

Front

What is the formula for the distance between two points in a coordinate plane?

Back

Distance = √((x2 - x1)² + (y2 - y1)²).
