The only thing I can think of to rewrite this is either 8+72t or changing the variable to a different letter. The expression is already in its simplest form.
Answer:
A. 5
Step-by-step explanation:
y2 - y1 / x2 - x1
5 - -5 / 3 -1 = 10/2 = 5
1) x-axis
2) line graph
I Can't really see the rest
The simplified expression is -3x^2 - 2x + 6. Hope this helps! ;)
