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>

Please help me with Alegbra 2!! Solve x2 + 4x + 1 = 0.
Julli [10]
x^2+4x+1=0\\\\\underbrace{x^2+2x\cdot2+2^2}_{(x+2)^2}-2^2+1=0\\\\use\ (a+b)^2=a^2+2ab+b^2\\\\(x+2)^2-4+1=0\\\\(x+2)^2-3=0\\\\(x+2)^2=3\iff x+2=\sqrt3\ or\ x+2=-\sqrt3\\\\\boxed{x=\sqrt3-2\ or\ x=-2-\sqrt3}
