Answer: 
Step-by-step explanation:
To find the slope of the line , we will write the equation in the form:
where:
slope
y - intercept.
To write 
in this form , we will make y the subject of the formula.
Subtract 4x from both sides
Divide through by 2
Therefore :

Answer:
5x - 2y = -2
Step-by-step explanation:
When subtracting one equation from the other, we are essentially just subtracting the left side of the second equation from the left side of the first equation and doing the same thing with the two right sides.
Here, we are subtracting (-7x + 3y) from (-2x + y):
(-2x + y) - (-7x + 3y)
Let's get rid of these parentheses. Remember that when we have a subtraction sign before a parentheses, we need to distribute a -1 to each term within those parentheses:
(-2x + y) - (-7x + 3y) = -2x + y + 7x - 3y = -2x + 7x + y - 3y = 5x - 2y
Now on the right side, we're subtracting 2 from 0:
0 - 2 = -2
Put it all together:
5x - 2y = -2
Hope this helps!

Answer:
5. Profit of Rs 1 per lemon
6. Rs 20
Step-by-step explanation:
5. Buy Rs 60 per 12 lemons = Rs 5 per lemon
Sell Rs 30 per 5 lemons = Rs 6 per lemon
Profit Rs 1 per lemon
6. Sell Rs 2500 per 100 pens = Rs 25 per pen
Profit per pen is 20% = (20/100)25 = 5
Cost price of a pen = 25 - 5 = 20
