The slope of the line is 2 = m. We can choose a coordinate pair and then plug that into the point-slope formula which is...
y - y1 = m(x - x1)
y - 3 = 2(x - 2)
Anyways, you could simplify more but the answer is C.
Good luck!

Answer:
D. 76.5
Step-by-step explanation:
The summation sign means that it is the sum of the expression for all values of n upto 6.
n = 2 below the summation sign means that n starts from 2.
∑(n-1)!/2 from n= 2 to n=6
= (2-1)!/2 + (3-1)!/2 + (4-1)!/2 + (5-1)!/2 + (6-1)!/2
= 1!/2 + 2!/2 + 3!/2 + 4!/2 + 5!/2
= 1/2 + 2*1/2 + 3*2/2 + 4*3*2/2 + 5*4*3*2/2
= 1/2 + 2/2 + 6/2 + 24/2 + 120/2
= 0.5 + 1 + 3 + 12 + 60
= 76.5
