Algebra 1 Fall Semester Final Exam Review

Front

What is the solution to the equation -3x + 6 = 2x - 4?

Back

x = 2

Front

What does the inequality y ≤ 2/5x + 1 represent graphically?

Back

It represents a region below or on the line y = 2/5x + 1.

Front

What is the range of the function g if it is defined as -1 ≤ y ≤ 5?

Back

The range is all values of y from -1 to 5, inclusive.

Front

What does a correlation coefficient of -0.26 indicate about the relationship between two variables?

Back

It indicates a weak negative correlation.

Front

What is the slope of the line represented by the equation y = 2x - 4?

Back

The slope is 2.

Front

How do you determine if a linear inequality is graphed correctly?

Back

Check if the shaded region corresponds to the inequality sign and if the boundary line is solid or dashed.

Front

What is the difference between a solid line and a dashed line in graphing inequalities?

Back

A solid line indicates that points on the line are included (≥ or ≤), while a dashed line indicates they are not (> or <).

Front

What is the y-intercept of the equation y = 2/5x + 1?

Back

The y-intercept is 1.

Front

How do you find the x-intercept of the equation y = 2x - 4?

Back

Set y to 0 and solve for x: 0 = 2x - 4, so x = 2.

Front

What does the term 'range' refer to in a function?

Back

The range refers to the set of all possible output values (y-values) of the function.
