Mathematical Equivalence

ON

Find the equation of the line in slope-intercept form.

• y = - 1/4x - 3

• y = 1/3x + 3

• y = - 1/4x + 2

• y = 1/3x -3

What is the point slope form equation for the given line?(Use blue point for formula)

• y + 3 = 3 (x + 4)

• y + 4 = -3 (x + 3)

• y - 4 = 3 (x - 3)

• y + 4 = 3 (x + 3)

A line with a slope of 1/2 passes through the point (3, 5). What is its equation in point-slope form?

What is the point slope form equation given the following points: (0,1) and (-2, -2)

Put this into standard form:

y = 3x + 2

• y + 3x = 2

• 3x + y = 2

• 3x - y = -2

• -3x + y = 2

Change the following equation to Standard Form
y + 2 = -3(x - 5)

• 3x + y = 17

• 3x + y = 13

• 3x + y = - 13

• 3x + y = - 17

What is the equation of the line?

• y = 0
• y = 1
• y = 2
• x = 1

What is the equation of this line?

• x=5
• y=5
• y=5x
• x=-5
