The rate of change of function 1 (a horizontal line) is zero.
The rate of change (slope) of function 2 is the x-coefficient, 8.
8 is 8 more than 0.
The 4th selection is appropriat:
8
Answer:
A racer has just completed his first lap at a speed of 198m/s. Now his speed decrease or he decelerateted at 195m/s after 2s of his completion of first lap, as soon as he saw a curve path(line segment R). He then moved at a constant speed of 195m/s for the next 2s(line segment s). Then the race track after 4s of the completion of first lap was straight, so the racer accelerated to 200m/s within 2s( line segment T) and traveled at a constant speed for the next 6s( line segment U). After 12s from the first lap completion, he immediately saw a curve track, so he decelerateted to the speed of 194m/s within 3s( line segment V).
Hope it helped.

Answer:
Step-by-step explanation:
Equation of a line:
The equation of a line has the following format:
In which m is the slope and b is the y-intercept.
Perpendicular lines:
When two lines are perpendicular, the multiplication of their slopes is -1.
Perpendicular to y=1/8x+2
This line has slope 
So, for the line we want to find the equation, we have that:
So
Find the equation of the line through point (1,−5)
This means that when 
. We use this to find b. So:
The equation of the line is:
The answer is the second option you are correct !
