Question 1061985: 1-which of the following equations passes through the points (2,4) and (-3,-6)?
2-Given 3y-4x=5 and 4y+6=3x
are these lines parallel,perpendicular or neither?
3-What is the equation of a line that choose:
passes through the point(4,-5)and is parallel to 3x+2y=12?

-which of the following equations passes through the points (2,4) and (-3,-6)?
slope = (4--6)/(2--3) = 10/5 = 2
Form:: y = mx + b
Solve for "b"::
4 = 2*2 + b
b =0
Equation:: y = 2x
--------------------------
2-Given 3y-4x=5 and 4y+6=3x
are these lines parallel,perpendicular or neither?
slope of 1st equation ? y = (4/3)x + (5/3) :: slope = 4/3
slope of 2nd equation ? y = (3/4)x - (6/4) :: slope = 3/4
Ans: neither
-------------------------------------------
3-What is the equation of a line that choose:
passes through the point(4,-5)and is parallel to 3x+2y=12?
slope = -3/2
Form :: y = mx + b
-5 = (-3/2)*4 + b
-5 = -6 + b
b = 1
Equation::y = (-3/2)x + 1
------------------------------
