Hello:<span>
the equation is : y = ax+b
the slope is a : a×(1/2) = -1......( perpendicular to a line with a slope of 1/2) because : -2x+4y =8...y=(1/2)x+2 ) </span>
<span>
a = -2 y=(-2x+b
the line that passes through (2,1) :1 = -2(2)+b
b =5
<span> the equation is : y = -2x+5</span></span>
Answer:
6 - 4i
Step-by-step explanation:
-4 + i = 10 - 5i
<u>+4 +4 </u>
i = 14 + 5i
<u>-5i -5i </u>
-4i = 14
i = -3.5
