Algebra Fall Semester Exam Review Day 2

Front

What is the range in a graph?

Back

The range refers to the 'y' values of a function, indicating the vertical extent of the graph. An open circle means the value does not include that number (use < and >), while a closed circle means it does include that number (use ≤ and ≥).

Front

What inequality represents the highest possible price of the skirt if Mrs. Scott spends no more than $120 on a jacket and a skirt, with the jacket costing $20 more than 3 times the price of the skirt?

Back

3x + 20 ≤ 120, where x is the price of the skirt.

Front

How do you write an equation in slope-intercept form?

Back

The slope-intercept form is written as y = mx + b, where m is the slope and b is the y-intercept.

Front

What does 'zero' refer to in a graph?

Back

'Zero' refers to the point where the graph crosses or intersects the x-axis.

Front

Write an equation of a line that passes through the point (-2,3) and is parallel to the line x = 4.

Back

The equation is x = -2.

Front

What is the slope of a line?

Back

The slope is a measure of the steepness of a line, calculated as the change in y over the change in x (rise/run).

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they have the same slope and will never intersect.

Front

How do you find the y-intercept of a linear equation?

Back

To find the y-intercept, set x = 0 in the equation and solve for y.

Front

What is the difference between an open circle and a closed circle on a number line?

Back

An open circle indicates that the number is not included in the range (use < or >), while a closed circle indicates that the number is included (use ≤ or ≥).

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, and A should be non-negative.
