# 1



3x%2B4y=-2 Start with the given equation


4y=-2-3x Subtract 3+x from both sides


4y=-3x-2 Rearrange the equation


y=%28-3x-2%29%2F%284%29 Divide both sides by 4


y=%28-3%2F4%29x%2B%28-2%29%2F%284%29 Break up the fraction


y=%28-3%2F4%29x-1%2F2 Reduce





# 2


y=mx%2Bb Start with the given equation



y-b=mx Subtract b from both sides



%28y-b%29%2Fx=m Divide both sides by x to isolate m

Answer:
So our answer is m=%28y-b%29%2Fx
