Question 122359This question is from textbook texas algebra 1
:
find the slope of a line perpendicular to the graph of each equation.
20. y= -3x
24. y= -8
Write and equation for the line that is perpendicular to the given line and that passes through the given point.
26. y= x-3; (4,6)
Hope you reply soon. this is the last chapter for this lesson! Thanks, much appreciated :D This question is from textbook texas algebra 1

20) Y=-3 HAS A SLOPE OF -3 THEREFORE A PERPENDICULAR LINE SLOPE=1/3.
24) Y=-8 HAS A SLOPE OF -8 THEREFORE A PERPENDICULAR LINE SLOPE=1/8.
26) Y=X-3 HAS A SLOPE OF 1 THEREFORE A PERPENDICULAR LINE SLOPE=-1.
6=-1*4+b
6=-4+b
b=6+4
b=10 THEREFORE THIS EQUATION IS:
Y=-X+10.
