What is the slope-intercept form of a line?

• Ax + By = C

• y = mx + b

• y - y1 = m(x - x1)

• y = Ax + By

Which of the following equations is written in STANDARD form?

• y=3x-5

• 3x+16=5y

• 2/3 x + 9/13 y = 21

• 5x+7y=-12

Convert the standard form equation into slope-intercept form.
4x - 3y = 15

Which equation in standard form represents this graph?

• -3x +2y = -6

• 3x + 2y = 6

• -3x - 2y= 12

• -3x + 2y = -12

What is the slope intercept from of this equation?

2x + 3y = 0

• y = -2x + 3
