You already hve the answer, but you do this by turning the equation into standard form. Since we are isolating y for each linear equation, we must first subtract the 4x and 3x on both sides. This should come out to y=-4x+219 and 2y=-3x+195. Since we have our first equation in standard form, all we have go do is divide 2 on both sides frome the second equation. Then you can solve by substitution (y=y)

Mode is 6

Option A is correct.

Step-by-step explanation:

We need to find the mode for the given data set:

6,8,3,5,6,4,7,7,0,1,6

<u>Definition of Mode</u>

  • Mode is the most repeating value of data set.

Finding mode of data set: 6,8,3,5,6,4,7,7,0,1,6

Arranging data in ascending order:

0,1,3,4,5,6,6,6,7,7,8

SO, most repeating value is 6

So, mode is 6

Option A is correct.
