Q1 slope=%28m%29=change+in+%28y%29%2Fchange+in+%28x%29
in the equation 2x+3y=7 when y=0 x=7/2 (7/2,0) when x=0 y=7/3 (0,7/3)
m=%28%287%2F3%29-0%29%2F%28%280-7%29%2F2%29=%287%2F3%29%2A%28-2%2F7%29=-2%2F3
the pependicular to m is -1%2Fm=%28-1%2A3%29%2F-2=3%2F2
Q2 y=3x-1. 1st the intercepts. when y=0 3x=1 x=1/3 (1/3,0)
when x=0 y=-1 (0,-1)
