2x+y= -5 is our equation and it passes through (4, -3)
point-slope formula= y-y1= m(x-x1)
fill in your formula, but flip the slope so its perpendicular. so slope is 1/2.
y+3=1/2(x-4) when i filled the formula in, i used 4 as x1 and -3 as y1.
y+3=1/2x-2 multiply x and -4 by 1/2
y=1/2x-5 subtract 3 from both sides.
Final answer: y=1/2x-5
Also, i'm sorry my answer took so long the bell rang and so I had to leave this alone for a minute. Feel free to ask any questions :)
