The equation in Slope-Intercept Form is y = -2/5 x + 4.
We have given that,
 y−2=−2/5(x−5)
We have to rewrite the equation in Slope-Intercept Form. 
<h3>What is the slope-intercept form of the line?</h3>
slope-intercept form is y = mx + b
for equation y - 2 = -2/5 (x - 5) we need to simplify/rearrange
so y - 2 = -2/5 x + -2/5 (-5)
 = -2/5 x + 2
=> y = -2/5 x + 4
This line has a gradient of -2/5 (goes down 2 units and across 5 units) and a y-intercept of 4 so passes through the point (0,4).

Step-by-step 
=> 900=-100x+300
=> -100x+300=900
=> -100x=900–300
=> -100x=600 divide both side by -100
=> x=-6
 
        
                    
             
        
        
        
The right answer is -2/3
