Forms of linear equations in two variables

What does "m" represent in y=mx+b?

• y-intercept
• slope
• macaroni
• nothing

Which of these represents point-slope form of a linear equation?

• y - y₁ = m(x - x₁)
• Ax + By = C
• y = mx + b

Which statement best describes "b"?

• x-intercept
• y- intercept
• Slope
• Bee

Identify the slope and y-intercept of:
y = 1/2x - 1

• slope: 1/2   y-intercept:  -1 
• slope: 2/1   y-intercept:  -1
• slope: 3   y-intercept:  -3 
• slope: 2  y-intercept:  5 

Put this into standard form:
y = 3x + 2

• y + 3x = 2
• 3x + y = 2
• -3x + y = 2
• 3x - 2y = 2

Which equation can you NOT read the slope from?

• Slope-intercept form

• Point-slope form

• Standard Form

Which equation can you read the y-intercept from?

• Standard form

• Slope-intercept form

• Point-slope form

Which equation is written in standard form?

• 6y = x + 5

• y-1 = 7(x - 2)

• y = 1/2x + 15

• 2x + 3y = 18

Which equation is NOT linear?

• x + y = 6

• 3y = 9

• x² + 4 = y

• y = 5x - 9

What is the slope in the equation: y=4x+3

• 3

• 4x

• 4

• x
