Dividing 3.6 by 0.25 follows the following generic approach : You have
to firstly need to multiply both divisor and dividend by that number
such that the divisor becomes a whole number first .
So we multiply both dividend and divisor by 100 such that the problem converts to 3.6*100/0.25*100 = 360 being divided by 25 .
So the approach to divide a number froma decimal number is to first
convert problem into dividing the number from a whole number , by
multiplying both the number and divisor from the approriate number .
Which was in above problem comes out to be 100 .
Answer:
y = m x + b equation for a straight line
m m' = -1 for perpendicular lines
Thus m' = -1/2 is required
Check:
-1/2 * -6 + 2 = = 3 + 2 = 5 = y for the last equation give
-12/2 = -6 = x
-12/-4 = 3 = y
The x intercept is -6 and the y intercept is 3
