Writing Equations in Slope-Intercept Form

What does the 'm' represent in the equation y = mx + b?

• The y-intercept

• The x-intercept

• The slope

• The constant term

How can you use the equation y = mx + b?

• To find the x-intercept

• To find the slope

• To graph the line

• To find the y-intercept

What is the formula for finding the slope from a table?

• m = y-intercept over x-intercept

• m = change in y over change in x

• m = x-intercept over y-intercept

• m = change in x over change in y

If the change in y is 2 and the change in x is 4, what is the slope?

• 1/4

• 4

• 2

• 1/2

How do you find the y-intercept (b) from a table?

• Multiply the slope by the x value

• Look at the value of x when y is 0

• Look at the value of y when x is 0

• Divide the change in y by the change in x

If the slope (m) is 1/3 and the y-intercept (b) is -1, what is the equation of the line?

• y = 1/3x - 1

• y = 1/3x + 1

• y = -1/3x - 1

• y = -1/3x + 1

What is the equation of a line if m = 1/2 and b = 1?

• y = 1/2x - 1

• y = 2x - 1

• y = 1/2x + 1

• y = 2x + 1

If the slope (m) is 1/5 and the y-intercept (b) is -3, what is the correct form of the equation?

• y = -1/5x - 3

• y = 1/5x + 3

• y = 1/5x - 3

• y = -1/5x + 3

How should you write the equation if m = 1 and b = 4?

• y = 4x - 1

• y = 4x + 1

• y = x + 4

• y = 1x + 4

What is the simplified form of the equation if m = 1 and b = 0?

• y = x

• y = 1

• y = 0x + 1

• y = 1x + 0
