Understanding Slope and Intercepts

This video tutorial teaches how to graph lines not in slope-intercept form by converting them into function notation. It covers solving two-step equations, graphing using slope-intercept form, and simplifying fractions. The tutorial also explores alternative methods to find the slope and y-intercept without converting to function notation.

What is the first step in solving a two-step equation like 3 + 2y = 7?

• Multiply both sides by 2

• Divide both sides by 2

• Add 3 to both sides

• Subtract 3 from both sides

In the equation y = 3x - 4, what does the number 3 represent?

• The x-intercept

• The y-intercept

• The slope

• The constant term

When graphing a line, what is the first point you should plot?

• Any random point

• The y-intercept

• The x-intercept

• The midpoint

What is a common mistake when simplifying fractions with two terms in the numerator?

• Subtracting the denominator from both terms

• Dividing only one term by the denominator

• Multiplying both terms by the denominator

• Adding the denominator to both terms

How do you convert the equation -4x + 2y = 12 to slope-intercept form?

• Add 4x to both sides and divide by 2

• Subtract 12 from both sides and multiply by 4

• Add 12 to both sides and divide by 4

• Subtract 4x from both sides and multiply by 2

How can you find the slope of an equation without converting it to slope-intercept form?

• By dividing the constant by the coefficient of y

• By taking the opposite of the coefficient of x divided by the coefficient of y

• By adding the coefficients of x and y

• By subtracting the coefficient of y from the coefficient of x

What is the y-intercept of the equation 3x - 6y = -12 without converting it to slope-intercept form?

• 1

• 2

• 3

• 4
