Answer:
Step-by-step explanation:
y = 3x is an example of such an equation.
Y = 2x - 3
Y = 2(2) - 3
Y = 4 - 3
Y = 1.
The y value or y coordinate is 1.
-10,-8,-4,2,6,7 is from least to greatest
The fraction would probably be the speed as well so here:
You do 20/45 which simplifies to 4/9
So the speed/fraction for this problem is 4/9 (feet per second)
P.S. I'm sorry if this is hard to understand
