Intercepts are when one value is 0...like when x is 0, the point would be the y intercept....
x intercept is 4
y intercept is 5
slope: y2 - y1/x2 - x1
slope = 0 - 5/4 - 0
slope = -5/4
the for the equation plug in any points from the line.
y = mx + b
5 = -5/4(0) + b
5 = B
y = -5/4x + 5 is the equationh to the line
Answer:

Step-by-step explanation:
4,800 divided 8 = 600
the total is 600 bottles
i hope this helps, have a great day. And good luck!
Answer:
The slope of a line is change in Y / change in X. The slope of a horizontal line = 0, not undefined. The slope of a vertical line = undefined.
Everything is in million acres, so we can just drop that while we work it out but just remember we have to add it back on at the end of the problem.
First year 3.42
Second year 8.71
Third year ???
Total 21.46
So...
3.42 + 8.71 + ? = 21.46
12.13 + ? = 21.46
? = 21.46 - 12.13
? = 9.33
The 3rd year 9.33 million acres were burned
*Note I put a ? for the unknown. I could have used x or y or anything else.
Answer:
y=-3(x-1)^2+5
Step-by-step explanation:
The vertex form of a parabola is y=a(x-h)^2+k where (h,k) is the vertex.
We are given the vertex (h,k) is (1,5) so that makes the equation we have
y=a(x-1)^2+5.
We still need to find a.
We do have the point (0,2) on our parabola.
So replace (x,y) with (0,2) and solve for a.
2=a(0-1)^2+5
2=a(-1)^2+5
2=a(1)+5
2=a+5
-3=a
So the equation is
y=-3(x-1)^2+5
