You can put this solution on YOUR website! Find an equation for the line perpendicular to the line 8x+3y= -2 having the same y-intercept as -8x+4y=2.
***
slope-intercept form of equation for a line: y=mx+b, m=slope, b=y-intercept
-8x+4y=2
4y=8x+2
y=2x+1/2
slope, m=2 y-intercept, b=1/2
..
For perpendicular line:
m=-1/2 (negative reciprocal)
equation: y=-x/2+1/2
see graph below:
