Look at a graph and write the equation using slope-intercept form.

Write the equation of a line given two points. Write the equation of a line given the slope and the y-

intercept. Find slope using two points. Write equations for parallel and perpendicular lines. Look at a scatter plot, draw a best-fitting line, and make

predictions. Use function notation. Solve linear systems.
