Question 1061731: 1-Find the equation of the line perpendicular to the line whose equation is 2y-4x=7 and which passes through the point (1,2)
2-Given 3y-4x=5 and 4y+6=3x.Are these lines parallel,perpendicular,or neither?

You can put this solution on YOUR website!
I suggest you try this and compare to slope-intercept equation form:

Linear equation in standard form, Ax%2BBy=C;
By=C-Ax
y=C%2FB-Ax%2FB
y=-Ax%2FB%2BC%2FB
highlight%28y=-%28A%2FB%29x%2BC%2FB%29

Identify the corresponding parts to y=mx%2Bb.

Use that to answer question #2.


You can use the same idea to help answer question #1. You can keep everything in standard form if you want. You need to know that the product of slopes of perpendicular lines is -1.
