Question 1024690: HI!
I have a math homework on linear equations, and I am stuck at question number 2.
Here goes the problem:
Given the point A(2,7) and the line l1 with equation 3x � 4y � 8 = 0
1. Find equation of the line AQ, which is perpendicular to l1 and passing through A.
2. Find the coordinates of point Q, which is the point of intersection between the line AQ and the line l1.
3. Calculate the length of [AQ].
4. On graph paper, plot the point A(2,7) and the line l1 with equation 3x � 4y � 8 = 0.
From point A, draw a perpendicular to the line l1. Let Q be the point of intersection between the perpendicular and the line l1. From your graph, measure the length [AQ] and compare it with the distance you previously calculated.
I have solved the first one and my answer is y= -4/3X + 25/3
As for questions number 4, I would appreciate it if you gave me some tips on how to draw the graph
Thanks in advance!!

Question 1024838: Hi, can someone check my answers? Thanks!
Find the equation of the line that contains the point (3,2) and that is:
a) parallel to the line containing the points (3,6) and (6,-9)
I got the answer y=-5x+17 by finding the slope first and then substituting the points (3,2) into the y=mx+b equation and solving for b.
b) perpendicular to the line containing the points (3,6) and (6,-9)
So the equation is the same as above except for the slope and I ended up getting y=-1/5x+13/5.
How does that look?
