Simple...
you have:
1.) Find the slope of the line using (-2,1) and (3,6)
Using


m=1 (slope)
2.)Tell whether the equation, 8y+3=5x+3, is a direct variation.
y=

(None)
3.)What is the slope and y-intercept of the graph of the equation y=2x+3?
Slope =2
y-intercept=3
C.
Thus, your answer.
Answer:
I think its D? I'm not sure sorry if I get it wrong
You would get 89/21 and then for a mixed number 4& 5/21
0=-16t^2 +64
0=-16(t^2 - 4)
0=-16(t-2)(t+2)
t=2 or - 2

I believe that none would be irrational; an irrational number can't have terminating or repeating decimals. 3/8= .375, (56/8)^4=7^4=2,401, 36^4/4^4=6561, and .19 repeating is a repeating decimal.
