You need slope and y- intercept. It is a negative slope because the line is going down from left to right. Count rise over run.
M = - 4/6 = -2/3
If the line continued to the y axis it would cross at 10.
y = -2/3x + 10
The answer to this equation will be 2.
Answer:
12.5%
Step-by-step explanation:
sum the parts of the ratio 1 + 3 + 4 = 8 parts
8 parts represents 100%, hence
1 part =
= 12.5% ← Andy's percentage of the total
A parabola is a mirror-symmetrical U-shape.
- The equation of the parabola is

- The focus is

- The directrix is

- The axis of the symmetry of parabola is:

From the question, we have:


The equation of a parabola is:

Substitute the values of origin and vertex in 



Collect like terms

Solve for a

Substitute the values of a and the vertex in 

The focus of a parabola is:

Substitute the values of a and the vertex in 




The equation of the directrix is:

So, we have:
----- the directrix
The axis of symmetry is:

We have:

Expand

Expand


A quadratic function is represented as:

So, we have:


Recall that:

So, we have:


This gives


Hence, the axis of the symmetry of parabola is:
