As shown in the graph, the line is a straight line. Therefore, the general equation of a straight line can be employed to derive the equation of the line.
The general equation of a straight line is given by:
y = mx + c <em>or            </em>-------------(i)
y - y₁ = m(x - x₁)        -----------------(ii)
Where;
y₁ is the value of a point on the y-axis
x₁ is the value of the same point on the x-axis
m is the slope of the line
c is the y-intercept of the line.
Equation (i) is the slope-intercept form of a line
Steps:
(i) Pick any two points (x₁, y₁) and (x₂, y₂) on the line.
In this case, let;
(x₁, y₁) = (0, 3)
(x₂, y₂) = (4, -2)
(ii) With the chosen points, calculate the slope <em>m</em> given by;
m = 
m = 
m = 
(iii) Substitute the first point (x₁, y₁) = (0, 3) and m =  into equation (ii) as follows;
 into equation (ii) as follows;
y - 3 =  (x - 0)
(x - 0)
(iv) Solve for y from (iii)
y - 3 =  x
x
y =  x + 3 [This is the slope intercept form of the line]
x + 3 [This is the slope intercept form of the line]
Where the slope is  and the intercept is 3
 and the intercept is 3
 
        
        
        
Answer:
The result is the number of years, approximately, it'll take for your money to double. For example, if an investment scheme promises an 8% annual compounded rate of return, it will take approximately nine years (72 / 8 = 9) to double the invested money
 
        
             
        
        
        
Let c represent the original amount that this guy had saved up.
He spent 25% of this amount, or 0.25c, on the printer. 
To progress further, we have to know how much the printer cost.
Supposing that the printer cost $100 (which we do not know as a fact), this would be equal to 0.25c.
Thus, his savings originally amounted to c = $100/0.25 = $400.
