Graphing Slope-Intercept Form Mastery

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

• It is the most complex form.

• It provides key information at a glance.

• It requires extensive calculations.

• It is rarely used in real-life scenarios.

In the slope-intercept form y = mx + b, what does 'm' represent?

• The slope

• The constant term

• The x-intercept

• The y-intercept

How is the slope of a line defined?

• As the horizontal change over vertical change

• As the vertical change over horizontal change

• As the sum of the x and y coordinates

• As the product of the x and y coordinates

What is the term used to describe the vertical change in the slope formula?

• Slope

• Delta X

• Rise

• Run

When graphing a line, why is it helpful to write the slope as a fraction?

• To avoid using whole numbers

• To convert it to a mixed number

• To easily identify the rise and run

• To make the equation more complex

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

• 0

• 1

• 2

• -2

If an equation is not in slope-intercept form, what must you do to find the slope and y-intercept?

• Add a constant term

• Solve for x

• Isolate y and simplify the equation

• Multiply both sides by x

How do you describe a line with a positive slope?

• It falls from left to right

• It rises from left to right

• It is horizontal

• It is vertical

What is the slope of a vertical line?

• Positive

• Negative

• Zero

• Undefined

Using the slope formula, what is the slope of a line passing through points (3, 4) and (7, 8)?

• 1

• 2

• 1/2

• 4
