To write 0.1 as a percentage you have to multiply it by 100 and then put the % sign at the end of it.
0.1 X 100 = 10%
        
             
        
        
        
k = - 3
given k +  =
 = 
subtract  from both sides of the equation
 from both sides of the equation
k =  -
 -  = -
 = -  = - 3
 = - 3
 
        
             
        
        
        
Answer:
 
 
Step-by-step explanation:
<u>Given </u><u>:</u><u>-</u>
- The slope of the line in the graph is 4.
And we need to find the equation of the line. On looking at the graph we see that , it cuts y axis at (0,3) .So the y Intercept of the equation is 3 . 
<u>Slope</u><u> Intercept</u><u> Form</u><u> </u><u>:</u><u>-</u><u> </u>
 
 
<u>Substituting</u><u> the</u><u> respective</u><u> values</u><u> </u><u>:</u><u>-</u><u> </u>
 
 
<u>Hence</u><u> the</u><u> </u><u>equation</u><u> of</u><u> </u><u>line </u><u>is </u><u>y </u><u>=</u><u> </u><u>4</u><u>x</u><u> </u><u>+</u><u> </u><u>3 </u>
