Answer:
V= -2000t + 20000
Step-by-step explanation:
Let m be the slope of our function :
- m=(20000-16000)/(0-2)= -2000
- so our function is V= -2000t + b
- b is the intitial price so b = 20000
- then : V= -2000t + 20000
Let's check :
- take the second year : V= -2000*2 +20000 = 16000
- that's true !

Answer: i think it’s distributive don’t kill me if it’s wrong
Step-by-step explanation:
Answer:
y= -2/5 x -4
Step-by-step explanation:
So the equation is y=mx+b. Where m=slope and b=y-intercept. To find b, you would see at what point does the line cross the y axis. That would be at -4 so, -4 would be the b or y-intercept. To find m, you would take two points on the line and use this equation:
m=(y2 - y1 )/(x2 - x1)
If you were using the points, (-10,0) and (0, -4) the equation would be:
m=(-4-0) / (0+10)
So, m= -2/5
The equation of the line would end up being:
y= -2/5 x -4
