True or False.
  1. To solve an equation graphically, we graph two functions, (each side of the equation.)
  2. The solutions are the -coordinates of the intersection points of the two graphs.
  3. To solve a formula that is linear in the desired variable, we must get all terms including that variable on one side of the equation.
  4. If two or more terms on one side of the equation include the desired variable, we factor it out.
