You can
put this solution on YOUR website!perpendicular lines, one that passes through the point (3,-4) and the other that passes through the point (7,2).
:
Choose a convenient slope and write an equation for the (3,-4) coordinates
Let m1 = 2
:
y - (-4) = 2(x - 3)
y + 4 = 2x - 6
y = 2x - 6 - 4
y = 2x - 10 is one line
:
Slope relationship of perpendicular lines: m1*m2 = -1
The slope of the second equation:
2*m2 = -1
m2 =
; coordinates (7,2)
:
y - 2 =
(x - 7)
y - 2 =
x +
y =
x +
+
y =
x +
is the 2nd line
:
Graphing this we have
:
You can check the equations by substituting the given values for x and finding y
