write an equation of the line containing the specified point and perpendicular to the indicated line?
(2,5),x22y=3

x 2 2y= 3
x 5 = 2y
y = x/2 5/2 The slope is 1/2, so the perpendicular slope to it would be 2.
For me, I find it easier to draw a graph. Find point (2, 5) and draw a line with slope of 2. Once you hit the yaxis, the number on the axis is you're yintercept. So the equation should be y = 2x 6 
y = .5x 2.5 or y= 1/2x 5/2
So the slope of your line is 2
y+5=2(x+2) y= 2x45 y=2x9 
And the winner is . . . the one which contains the given point.
2(2)  6 = 46 = 2 Bzzt!
2(2)  9 = 4  9 = 5 Ding Ding!
