Answer:
y=1.5x
Step-by-step explanation:
Use the equation y-y1=m(x-x1)
y-9=1.5(x-6)
y-9=1.5x-9
y=1.5x
Answer:
Roughly 2857.14
Step-by-step explanation:

The given equation is a Quadratic equation, so it's graph must be a parabola, and the Coefficient of x² is positive that means the parabola must have an opening upward.
And 2 is added to the ideal equation, so the parabola must have shift 2 units up from x - axis.
From the above information, we can easily conclude that the Correct representation is done in graph 4
6 is only the double of 3
3×2=6
Any number that's multiplied by 6 will be the double of any number multiplied by 3, or vice versa, any number multiplied by 3 will be half of any number multiplied by 6. This is because 6 is a multiple of 3.
Take for example:
850×6=5100 ⇔ 850×(3×2)=5100
Again, a spreadsheet or suitable calculator makes this short work.
The sum is 184.
_____
The terms being summed are ...
2·3² +3 = 2·9 +3 = 18 +3 = 21
2·4² +3 = 35
2·5² +3 = 53
2·6² +3 = 75
Their total is
21 +35 +53 +75 = 184
