Algebra 1 Chapter 3 Review: Adding and Subtracting Rational Expressions

The video reviews graphing techniques for lines, including using tables, intercepts, and slope-intercept form. It explains vertical and horizontal lines with Vox and Hoy, discusses slope calculation, and introduces functions with tests like the vertical line test. Function notation and domain/range concepts are also covered.

What is the first step in graphing a line using a table?

• Draw the graph

• Select values for X

• Rearrange the equation to get Y by itself

• Choose any numbers for Y

How do you find the x-intercept using the cover-up method?

• Multiply both sides by X

• Cover the X and solve for Y

• Cover the Y and solve for X

• Divide both sides by Y

What does the slope-intercept form of a line look like?

• X = MY + B

• MX - Y = B

• B = Y - MX

• Y = MX + B

What does 'Vox' represent in graphing?

• Slope of a line

• Horizontal line

• Vertical line

• X-intercept

How is slope calculated?

• Rise over Run

• Run over Rise

• Y-intercept over X-intercept

• X-intercept over Y-intercept

What does the vertical line test determine?

• If a graph represents a function

• The slope of a line

• The x-intercept of a line

• If a line is vertical or horizontal

What does 'F of negative 2 equals negative 7' signify in function notation?

• The x-value is -7 and the y-value is -2

• The function's name is F, the x-value is -2, and the y-value is -7

• The function's slope is -2 and the y-intercept is -7

• The function's name is -7 and the x-value is -2

How do you find the value of x when F of x is -13?

• Substitute -13 for y and solve

• Substitute -13 for x and solve

• Multiply x by -13

• Divide x by -13

What does the domain of a function represent?

• The slope of the function

• The input values

• The range of the graph

• The output values

What is the range of a function?

• The minimum value of Y

• The maximum value of X

• The input values

• The output values
