Write the equation of a line perpendicular to y = -5/6x -3 and whose y-intercept is (0,11). i fr need ..

Hey!

A perpendicular line has the slope as the negative reciprocal of the given line, so therefore the new lines slope would be...

y = 6/5x + b

Now to find the y-intercept you will have to just plug in the given point/coordinate in the equation above and solve for b...

11 = 6/5(0) = b

11 = b

Put the given slope and y-intercept in a slope intercept form equation (slope intercept form is y = mx + b)...

y = 6/5x + 11

This new equation is:

1) perpendicular to the given equation

2) in slope intercept form

y = 6/5x + 11

Hope this Helped!

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18
