When graphing, what do you do after you graph your y-intercept?

• Find slope and start with your run(left or right) then to rise (up or down)

• Find slope and start with your rise (up or down) then to run (left or right)

• Draw a vertical line

• Draw a horizontal line

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

• y - y₁ = m(x-x₁)

• Ax + By = C

• y = mx + b
