Answer:
D. y=-1/5(x)
Step-by-step explanation:
To find the equation of a line, use the formula y=mx+b, where x and y represent your x and y coordinates, m is your slope and b is your y-intercept.
b is you y-intercept, this is where the line cuts the y-axis. We can see from the graph that the line cuts the y-axis at (0,0), so c=0.
Now we have y=mx
Sub in one of our points (10,-2):
-2=m10
m=-1/5
So our equation looks like this:
y=-1/5(x)
f(x) = x2 - x + 2
f(-1)=(-1)²-(-1)+2=4 contain the point (-1,4)
f(0) = 0²-0+2 = 2 contain the point (0,2)
f(2) = 2²-2+2 =4 contain the point (2,4)
Answer:
No, it is D.
Step-by-step explanation:
<em>It can not be A or C, because length can not be negative</em>
Because the y is the same, you only have to <em>count the distance of the x-axises</em>.
4 - (-3) is 7 units, which is D.
For the first problem, the answer is D, because every year, the graph goes down by about $4,500.
For problem two,
a. It's located in quadrant one because x and y are both positive (I've attached a graph with labeled quadrants for reference)
I'm unsure about b and c but I hope I helped with the others!
