When you have lines in graphs for ex
Y=2x+7
2x is the rate of change
7 is the instant amt if the x=0 (or the y-intercept)
The answer is A. I just finished the test.
-8/5 is a rational number because in order to be a rational number it must be able to be written as a fraction. -8/5 is a fraction; therefore, the negative does not affect it.
18 - 5z + 6z > 3 + 6
18 + z > 9
- 18 - 18
z > -9
Solution Set: (-9, ∞)
The symbol they are using is that of a ray so, order matters.
Ray BC is telling you the ray starts at point B like a line segment BUT continues on towards and through point C rather than stopping at it.
Ray CB is telling you just the opposite; the ray starts at point C, continues on towards and through point B.
