Y = 5x + 7<br> 2x + y = -5<br> Are the equations parallel,<br> perpendicular, or neither?
Nezavi [6.7K]

Lines are neither perpendicular nor parallel.

Step-by-step explanation:

Step 1:

In equation 1, Y = 5X + 7

In equation 2,  Y = -2X -5

Step 2:

Slope Intercept form Y =mX +c

Where m = Slope

Slope of line 1 = 5

Slope of line 2 = -2

m1  is not equal to m2. Hence it is not parallel.

m1  × m2 is not equal to -1. Hence they are not perpendicular.

The first and third quartiles
aalyn [17]
1.  You'll need to download this data, or copy it down by hand.
2.  Rearrange the data from lowest to highest values.
3.  You have 24 data points (an even number). 
       In this case, to find the 1st quadrant, take the left half (that is, the left 12) data points.  Since 12 is an even number, you must find the average of the middle two of these 12 data points.  Your result is the 1st quadrant.
      To find the 3rd quadrant, find the middle two data points of the right-hand 12 data points.  Average these two points.  The result is the 3rd quadrant.
