Writing Equations in Slope-Intercept Form

What letter is used to represent slope in the slope-intercept form?

• M

• A

• X

• B

How is slope calculated?

• Sum of rise and run

• Run over rise

• Difference of rise and run

• Rise over run

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

• Y-intercept

• X-intercept

• Origin

• Slope

If the slope (m) is -2 and the y-intercept (b) is 5, what is the equation in slope-intercept form?

• y = 2x - 5

• y = -2x - 5

• y = 2x + 5

• y = -2x + 5

Given a slope of 4 and a y-intercept of -3, what is the correct equation?

• y = 4x + 3

• y = -4x + 3

• y = -4x - 3

• y = 4x - 3

How do you find the slope from a graph?

• By counting the number of points

• By adding the coordinates

• By calculating rise over run

• By measuring the distance between points

If a line crosses the y-axis at 3 and has a slope of -2/5, what is the equation?

• y = 2/5x - 3

• y = -2/5x - 3

• y = 2/5x + 3

• y = -2/5x + 3

What is the y-intercept if the line crosses below the x-axis at -2?

• 0

• 1

• -2

• 2

What is the equation of a vertical line passing through x = 3?

• y = 3

• x = -3

• y = -3

• x = 3

What is the equation of a horizontal line passing through y = 3?

• x = 3

• y = 3

• y = -3

• x = -3
