Multiply the numerator and denominator by 4+5i
=[(2+3i)(4+5i)]/[(4-5i)(4+5i)]
=[(8-15)+(12+10)i] / [16+25] <span>= [ -7 + 22i ] / [41]
= (-7/41) + (22/41)i </span>
first you put this equation into y=mx+b form then you look at the slope of the equation. if both of the slopes are same then its parallel.
-15m -30 = -12m +6
3m = 36
m= 36/3 =12
C. 17 r 1 is the correct answer
