Paralell means has same lsope
y=mx+b
m=slope
given
y=3x-5
slope=3
y=3x+b
find b
(3,1)
x=3
y=1
sub and find b
1=3(3)+b
1=9+b
minus 9 both sides
-8=b
y=3x-8 is equation
Answer:
Step-by-step explanation:
This is the image of the graph you determine if that's perpendicular.
Perpendicular definition - In elementary geometry, the property of being perpendicular is the relationship between two lines which meet at a right angle. The property extends to other related geometric objects. A line is said to be perpendicular to another line if the two lines intersect at a right angle.
