Write the equation of the line
What is y = 2x + 3
Describe the transformation.
90 degree rotation clockwise
or

Write in slope intercept form
6y-3=10x
What is y =5/3x +1/2
Identify the y-intercept of the equation x=5
Trick Question. There is no y-intercept because the line x=5 never crosses the y axis.
Write the equation for the line
Rotation 270 counterclockwise or 90 degrees clockwise followed by a translation up
