Perpendicular lines have slopes that are opposite and reciprocal. Therefore, the line we are looking for has a -3 slope.
y= -3x+b

Now, we can substitute in the point given to find the intercept.
2= -3(4)+b
2= -12+b
b=14

Finally, put in everything we've found to finish the equation.
y= -3x+14

17-2p=2p+5+2p ? I’m so confused
svp [43]

Answer:

Step-by-step explanation:

Let's do like-terms first which on the right side has the 2p:

17-2p=4p+5

Then make the variables on one side:

17=4p+2p+5

17=6p+5

Let's put that 5 on the other side:

17-5=6p

12=6p

Lastly, divide 6 to get a final remaining p.

12/6=p

2=p

Hope you understand :)
