Answer:
Here is what I did
Step-by-step explanation:
 
        
             
        
        
        
I believe it was a rectangle I'm not sure test it out.
        
                    
             
        
        
        
It would be: 420 + (420 * 17.5%)
= 420 + (420 * 0.175)  [ 17.5% = 0.175 ]
= 420 + 73.5
= 493.5
In short, Your Answer would be <span>£493.5

Correct answer: y =  x + 2
x + 2
To find out the slope, you would need to remember this slope formula:  . We can use the two points provided on the graph to figure out the slope. We can label (3, 3) as
. We can use the two points provided on the graph to figure out the slope. We can label (3, 3) as  and
 and  , and (0, 2) as
, and (0, 2) as  and
 and  . Now we can plug these numbers into the slope formula to find out the slope:
. Now we can plug these numbers into the slope formula to find out the slope:
m =  →
 →  →
 →  →
 → 
To find out the y-intercept, just substitute (3, 3) into the slope-intercept<em> </em>formula ( <em>y = mx + b</em> ) with the slope that is substituted for '<em>m</em>' that we already solved earlier. 
y = mx + b
(3) =  (3) + b
(3) + b
3 = 1 + b
2 = b
You can also prove this true by looking at the graph provided. The line intersects at the y-axis at 2.
Now we know that m =  and b = 2, we can substitute it into the slope-intercept formula. Thus, the answer is y =
 and b = 2, we can substitute it into the slope-intercept formula. Thus, the answer is y =  x + 2.
x + 2.
