Answer:
i think its 0.0225
Step-by-step explanation:
The correct answer is A) y = -3x - 1
In order to find this, start by using the two points on the line to find the slope.
m(slope) = (y2 - y1)/(x2 - x1)
m = (-4 - 2)/(1 - -1)
m = -6/2
m = -3
Since A is the only one with a -3 slope, this is the correct answer.
<u>Answer: </u>
Option (c)
The average speed between 2.8 km and 4.2 km is 42 km/h
<u>Explanation:</u>
Given, the distance between 2.8 km and 4.2 km is 4.2 - 2.8 = 1.4 km
Time (in hours) between 2.8 km and 4.2 km
= 0.084 – 0.051
= 0.033 hr
Speed =
Speed = 
Speed = 42.4 km/hr = 42 km/h (rounded to nearest)
Therefore, the average speed between 2.8 km and 4.2 km is 42 km/hr
Hence, Option (C) is correct
F(x)=-2x+8
This is because f(x) is the same as writing y so therefore you have to change the equation to 4x+2y=16 so you have Y=-2x+8
