Look at this problem, and remember that parallel lines have the same slope, and the slope of perpendicular lines are negative inverses.
==================================================================
Find the slope and y intercept of the line, and graph:
2x+3y=18
I got the slope as: -2/3
and the y intercept as: (0,6) is this correct? Also how do I graph that?
-------------
Solve for y, --> slope-intercept form y = mx + b
y = (-2/3)x + 6
m = -2/3 (slope)
b = 6 (y-intercept)

A) Y = -1/2x + 5
B) Y = 2x - 5
C) y = 1/2x - 2
D) Y = -1/2x + 5/2
2) Determine whether the graphs of the given equations are parallel, perpendicular, Or nither

A) Parallel
B) Perpendicular
C) Niether
-----------------------
Find the slope of the 2 graphs.
Y = -2x + 3
2x + Y = 7 ---------- Solve for y
y = -2x + 7
The slope is -2, same as the 1st equation.
---> parallel.
=====================================================
3) Determine whether the graphs of the given equations are parallel, Perpendicular, Or niether
Y = x + 11
Y = -x - 2
A) Parallel
B) Perpendicular
C) Niether
The slope of the 1st eqn is +1
The slope of the 2nd eqn is -1
They are negative reciprocals ----> perpendicular.
=======================================================
4) Determine whether the graphs of the given equations are parallel, Perpendicular Or nither
Y = -2x + 3
2x + 4y = 0
A) Parallel
B) Perpendicular
C) Niether
Solve the 2nd eqn for y. then the slope is the coefficient of x.
============================
5) Determine whether the given equations are parallel, Perpendicular, Or Niether
Y = 4x - 2
-x + 4y = 0
A) Parallel
B) Perpendicuar
C Niether
---
Solve the 2nd eqn for y. then the slope is the coefficient of x.
If the slopes are equal, they're parallel.
If the product of the 2 slopes = -1, they're perpendicular.
otherwise, neither.
