Find b of y = mx + b first using a modified version of the equation.
b = y - mx
b = -1 -(1.2×-3)
b = 13/5 = 2.6
y = 1.2x + 2.6 ← result of substituting values of m and b into y = mx + b
-1.2x + y = 2.6 ← result of subtracting 1.2x from both sides
12x - 10y = -26 ← result of multiplying previous equation by -10
6x - 5y = -13 ← result of dividing previous equation by 2
ANSWER: 6x - 5y = -13

Answer: Median = 7</h3>
=======================================================
Explanation:
Sort the values from smallest to largest. Doing so leads to the list {1,4,6,8,8,9}
Since the set is small enough, you can probably notice that the middle most number is a tie between the 6 and the first 8. The midpoint is (6+8)/2 = 14/2 = 7.
The median is 7.
---------------
If you wanted, you could cross off the first and last items of the set
That means we go from {1,4,6,8,8,9} to {4,6,8,8}
Then repeat to get the smaller set {6,8}
This shows we have a tie between the 6 and 8 as the middle most item, and why 7 is the median (since 7 is the midpoint between 6 and 8).
Answer:
7x + 2y = 9
Step-by-step explanation:
standard form is always written as:
Ax + By = C
To get the answer you would:
Multiply 525 by 1.2 525*1.2=
which equals 630
then you would add 525 to 630 525+630=
So the answer would be:
1155
Hope this helps
The answer is C to this question
