Observing there is a difference of +8 between each f(x).
The slope of this sequence is 8.(y2-y1)/(x2-x1)
Using the point slope equation,
y-y1 = m(x-x1) yields
y = 8x -4 as the answer.
A. The equation is true.
67+33=100
70+30=100
100=100 so yes, the equation is equal.
1. Is correct
2. x^2 - 12
3. 2 / (a-1)
