-5216, -3.2, -3.12, 8
The point-slope form:

m - slope
(x₁, y₁) - point
The formula of a slope:

We have the points (-2, 7) and (1, 1). Substitute:

<em>point-slope form</em>
<em> slope-intercept form</em>
<em>standard form</em>
Answer: Heater -Rs 2400; Fan- Rs 1600
Step-by-step explanation:
Given
Ajay bought a fan and a heater for Rs 4000
Suppose the price of fan is x and that of heater is 4000-x
Profit on the fan is 
Loss on heater is 
Total profit is 7% i.e. 

Thus, the price of heater is 
Price of fan is 
Price of heater is 
Yes, it is. To find this out, you need to make the denominators the same. They can both multiply into 15, so we change the denominators to 15. Whatever we do to the bottom, we also have to do to the top.
2/3 = 10/15
1/5 = 3/15
We can then see that 10 is more than 3 :)
