which of the following lines is not parallel y=2x=1
1)4x-2y=-4
2)2y-x=-4
3)y-2x=6
4)2x-y=-4
y=2x=1 is not an equation of a line.
Please clarify the typo.
To determine which of the following lines is not parallel to the line y = 2x + 1, we can compare the slopes of each line to the slope of y = 2x + 1.
The given line y = 2x + 1 is in slope-intercept form (y = mx + b) where the slope (m) is 2.
Let's rewrite each of the given lines in slope-intercept form to compare their slopes to the slope of y = 2x + 1:
1) 4x - 2y = -4
-2y = -4 - 4x
y = 2x + 2
2) 2y - x = -4
2y = x - 4
y = (1/2)x - 2
3) y - 2x = 6
y = 2x + 6
4) 2x - y = -4
-y = -4 - 2x
y = 2x + 4
Now, let's compare the slopes:
1) The slope is 2. This line is parallel to y = 2x + 1.
2) The slope is 1/2. This line is not parallel to y = 2x + 1.
3) The slope is 2. This line is parallel to y = 2x + 1.
4) The slope is 2. This line is parallel to y = 2x + 1.
So, line 2) 2y - x = -4 is the line that is not parallel to y = 2x + 1.
