Write the equation of a line with slope 2/3 and passing through (-1, 4)
y –y1=m (x–x1)y – 4 = 2/3 (x + 1)y – 4 = 2/3x + 2/33y – 12 = 2x + 22x – 3y = -14Standard Form

Write an indirect proof: Given: John drives 120 miles in 2 hours Prove: John exceeded the 55 mph speed limit
Assume temporarily that John did NOT exceed the 55 mph speed limit. In 2 hours, John would travel 110 miles. But this contradicts the fact that he drove 120 miles (from the given) so our assumption was false and John DID exceed the 55 mph speed limit… bad John!
