The slope is 4/3.
rise/run
rise = 4
run = 3
The slope is m=5/4 and the y-intercept is b= -10
-6t²+t+6
1. Let's group terms like, after eliminating the parentheses.
(3t²+6t+1)+(-9t²-5t+5)
3t²+6t+1-9t²-5t+5
3t²-9t² +6t-5t +5+1
-6t²+t+6
This is the simplest and most convenient form since there' s already a coefficient 1 in term "t".
2x + 4x - 3x - 6x = -3x
When x = 3,
-3x = -3(3) = -9
