Understanding Slope-Intercept Form

What is the slope in the equation y = 2x + 1?

• 1

• 2

• x

• y

In the equation y = 1/2x + 3, what does the number 3 represent?

• Y-intercept

• Coefficient of x

• X-intercept

• Slope

How do you convert the equation -4x + y = -10 to slope-intercept form?

• Add 4x to both sides

• Divide both sides by 4

• Subtract 4x from both sides

• Multiply both sides by 4

What is the slope of the equation y = -3x + 9?

• -9

• 9

• -3

• 3

When graphing y = -3x + 9, where do you place the first point?

• At (-3, 9)

• At (9, 0)

• At (0, 9)

• At the origin

In the context of the cookie sales problem, what does the slope of 5 represent?

• Total revenue

• Total cost

• Revenue per dozen

• Cost per dozen

What does the y-intercept of -75 represent in the cookie sales problem?

• Loss

• Profit

• Initial revenue

• Initial cost

How can you simplify the graphing process for the equation y = 5x - 75?

• Change the slope
