Answer:

Its a right angle triangle so trigonometry is used.
a is the hypotenuse, b is the adjacent.
Use sin to find a. Use tan to find b.
 
        
             
        
        
        
The sign of "b" on the numerator should be negative. So we conclude that the correct option is false.
<h3>Is the equation in the image correct or incorrect?</h3>
For a quadratic equation of the form:

By using the Bhaskara's formula, the solutions of the equation:

Are given by the formula:

Notice that the sign of the first term on the numerator should be negative, while on the image it is positive.
So the equation shown in the image is incorrect.

<h3><u>
Answer:</u></h3>
Hence, the equation of line is:
y= -6x
<h3><u>
Step-by-step explanation:</u></h3>
Clearly from the graph we could see that the line passes through the point (0,0) and (-1/2,3).
Also we know that the equation of a line passing through (a,b) and (c,d) is given as:

Here we have:
(a,b)=(0,0) and (c,d)=(-1/2,3)
Hence, the equation of line is:

Hence, the equation of line is:
y= -6x
 
        
        
        
You reduce it to 1/6 because 6 goes into 6 once and 6 goes into 36 six times giving you 1/6
