Change the equations of the lines so that the coefficient of [[$ x $]] becomes an integer.

a) [[$ \displaystyle\frac {1} {2}x – y + \displaystyle\frac {3} {2} = 0 $]]

Answer: = 0

b) [[$ \displaystyle\frac {3} {4}x + 2y + \displaystyle\frac {1} {4} = 0 $]]

Answer: = 0

c) [[$ \displaystyle\frac {1} {10}x – 3y + 2 = 0 $]]

Answer: = 0

d) [[$ \displaystyle\frac {5} {11}x + y = 0 $]]

Answer: = 0
