What is the standard form of the line?

• y = mx + b

• Ax + By = C

• y - y₁ = m(x - x₁)

• x/b + y/a = 1

What is the point slope form of the line?

• y = mx + b

• Ax + By = C

• y - y₁ = m(x - x₁)

• x/b + y/a = 1

Given the slope and the y-intercept of the line, write the equation in slope-intercept form.

slope = -3

y-intercept = 2

• -3x + 2y = 0

• y = -3x + 2

• y = 2x - 3

• y - 2 = -3(x - 2)
