Slope-Intercept Form Quiz

What is the first step in writing an equation in slope-intercept form when given a slope and a point?

• Calculate the midpoint

• Substitute the slope and point into y = mx + b

• Find the x-intercept

• Determine the slope

In the second example, what is the slope used to write the equation?

• 1/2

• 2

• -3

• 3

What formula is used to calculate the slope when given two points?

• y = mx + b

• m = (x2 - x1) / (y2 - y1)

• x = my + b

• m = (y2 - y1) / (x2 - x1)

When finding the y-intercept using two points, why is it important to be consistent with the points used?

• To ensure the slope is positive

• To make the equation simpler

• To avoid calculation errors

• To find the x-intercept

In the real-world example, what do the x-values represent?

• The cost of gasoline

• The number of gallons

• The months of the year

• The total budget

What is the slope of the line in the real-world example involving gasoline costs?

• 1.88

• 0.22

• 3.20

• 0.42

How is the y-intercept found in the real-world example?

• By substituting a point into y = mx + b

• By using the slope formula

• By finding the midpoint

• By calculating the average cost

What is the predicted cost of gasoline in October according to the real-world example?

• $2.20

• $1.88

• $4.08

• $3.20

In the real-world example, how much does Malik need to add to his budget for October?

• $0

• $5

• $10

• $2

What is the final equation of the line in the real-world example?

• y = 0.42x + 3.20

• y = 3.20x + 0.42

• y = 1.88x + 0.22

• y = 0.22x + 1.88
