Understanding Slope-Intercept Form

What is the formula for the slope-intercept form of a line?

• y = m/x + b

• y = ax^2 + bx + c

• y = mx + b

• y = a/x + b

In the equation y = mx + b, what does 'm' represent?

• The slope of the line

• The y-intercept

• The constant term

• The x-intercept

How do you isolate y in the equation 3x - 4y = 8 to convert it to slope-intercept form?

• Multiply both sides by 4

• Add 3x to both sides

• Divide both sides by 3

• Subtract 3x from both sides

What is the slope of the line represented by the equation y = 3/4x - 2?

• 4/3

• -2

• 2

• 3/4

When graphing a line, why is it important to plot the y-intercept first?

• It is the midpoint of the line

• It is the highest point on the graph

• It is a point that lies on the y-axis

• It determines the slope of the line

What does a positive slope indicate about the direction of a line on a graph?

• The line goes up from left to right

• The line goes down from left to right

• The line is vertical

• The line is horizontal

In the equation y = -1/2x + 4, what is the y-intercept?

• -1/2

• 4

• -4

• 0

How does a negative slope affect the direction of a line on a graph?

• The line goes up from left to right

• The line is vertical

• The line is horizontal

• The line goes down from left to right

What is the recommended method for using slope to find another point on a graph?

• Rise up or down based on the slope sign and always run right

• Always rise down and run right

• Rise up or down based on the slope sign and always run left

• Always rise up and run left

What should you do if you find a method for graphing lines that you prefer over the suggested one?

• Avoid using any method

• Combine both methods

• Use the method you prefer

• Stick with the suggested method
