Two points are given from each of two lines. Without graphing the points, determine wheather the lines are parallel, perpendicular or neither.
Line 1: (4, -6) (3, -2)
Line 2: (3, -1) (7, 0)
This is what I did.
-2 - (-6) = 4
3- 4 = -1
0 - (-1) = -1
7 - 3 = 4
Would it be perpendicular?
Write the slope-intercept form of each line. Then determine wheather the graphs of the lines are parallel, perpendicular, or neither.
4x + 2y = 8
2x + y = 1
This is what I did
4x + 2y = 8 / 2
y = -2x + 1
slope-intercept form: y= -2x + 4
slope-intercept form: y= -2x + 1
Is it parallel?
Thanks
