Area of a triangle: A= 1/2(base)(hieght)
base=x
height= 6(base)+1= 6x+1
13= 1/2 × (x)(6x+1)
(get rid of 1/2 by multiplying each side by 2)
26= (x)(6x+1)
26= (x × 6x)= 6x² (x × (+1))= x
26= 6x² + x
0= 6x²+x-26
Are either of those the answers? If not, list the options and I will be able to tell you which one is correct. Hope this helped!
You can take two of the x and y on the table to find the slope:
y2 - y1 / x2 - x1
Lets use (3, 12) and (4, 15)
15 - 12 / 4 - 3
3/1
The slope is 3
Now you can use the point-slope formula to find the equation: y - y1 = m(x - x1)
y - 9 = 3(x - 2)
y - 9 = 3x -6
y = 3x + 3
So you are correct with choice B.

I believe the answer would be 168

Step-by-step explanation:
Vertical lines are always undefined because if your answer has to be divided by zero, the answer is an undefined operation.
Horizontal lines always have the slope of zero!
