Answer:
or, y + 4 = m (x - 7) + c is the given equation.
Step-by-step explanation:
Here, the slope of the equation = -5
⇒m = -5
The given point is (7, -4)
⇒
Now, the general form of the equation is :
: c = arbitrary constant
So, the given equation becomes
or, y+ 4 = m (x - 7) + c is the given equation.
Here, m = the slope of the equation.
<u>Answer:</u>
(i) Total cost of the flat is Rs. 540000.
(ii) Expenditure incurred on labour is Rs. 150000
<u>Step-by-step explanation:</u>
According to the question, cement cost is Rs. 112500, which represents 75° in the pie chart.
(i) The total cost of the flat is represented by the total 360° in the pie chart.
∴ Using unitary method
75° represents Rs. 112500
⇒ 360° represents = × 360
= Rs. 540000
∴ Total cost of flat = Rs. 540000
(ii) Similarly, to calculate the cost of labour, represented by 100° in the pie chart, we can use the unitary method:
75° represents Rs. 112500
⇒ 100° represents = × 100
= Rs. 150000
∴ Cost of labour = Rs. 150000
