The slopes of 2 perpendicular lines with be reciprocals with the opposite sign.
For example if you have the equation y=-5x+2, your slope is -5. In a line perpendicular to y=-5x+2, your slope would be 1/5. As for finding b in y=mx+b for your second equation, I would need more specific information.
Hope it helps!
Answer:
x=14
Step-by-step explanation:
you should set up your problem like this:
5x=3x+28
use order of operations aka PEMDAS to solve
you're answer is 14
In one hour he would cycle 18Km, therefore in a 1/4 hour the cyclist would ride a 1/4 of 18 = 4.5Km.
Answer:
y=2/3x +b
-3=2/3(1)+b
b=-11/3
y=2/3x+(11/3)
y=2/3x-11/3
Step-by-step explanation:
Given the slope and one point on the line we use the formula above.
