A survey found that women's heights are normally distributed with mean 62.8 inches and standard deviation of 3.7 inches. This survey also found that men's heights are normally distributed with a mean 68.1 and a standard deviation 3.5. Most of the live characters employed at an amusement park have height requirements of a minimum 57in a d a maximum 64in.
A.Find the percentage of men meeting the height requirement
B. If the height requirements are changed to exclude only the tallest 50% of men and the shortest 5% of men, what are the new height requirements?

You left off the choices but we don't need them.  

The point slope form, a line with slope m through (a,b), is

y - b = m(x-a)

We have m=1.8 and (a,b)=(-4.5,1.4) so

y - 1.4 = 1.8(x  + 4.5)

You'll have to find that one among the choices yourself.

We solve for y to get the slope intercept form

y = mx + (b - ma)

Here we have m=1.8 and (a,b)=(-4.5,1.4) so

y = 1.8x + (1.4 - 1.8(-4.5))

y = 1.8x + 9.5
