Linear Equations

What is standard form of a line?

• y = mx + b

• Ax + By = C

• y - y1 = m(x - x1)

• y = Ax + By

Which equation is written in STANDARD form?

• y = 1/2x + 2
• y - 3 = -5(x + 2)
• 7x + 2y = 9

• 3x + 2 = y

Put this into standard form:

3x = 7y - 5

• 3x - 7y = -5

• 3x - 7y = 5

• 3x + 7y = 5

• 3x + 7y = -5

Put this into standard form:

y = 3x + 2

• y + 3x = 2

• 3x + y = 2

• 3x - y = -2

• 3x - 2y = 2

• y-intercept

• measurement

• slope

• nothing

• y-intercept

• nothing

• slope

• base

What is the equation of a line with a slope of 4 and a y-intercept of 2?

• y = -4x + 2

• y = -2x + 4

• y = 4x + 2

• y = 2x + 4

Write the equation for the line in slope-intercept form.

• y= -1x+3
• y= 4x+3
• y=1/4x+3
• y= -4x+3

What type of slope?

• negative
• steep
• undefined
• zero slope

What type of slope?

• undefined
• positive slope
• negative slope
• zero slope
