The unknown is the distance in kilometres
The given is the distance in miles=140 miles
1 mile=1.6093km
140 miles=?
140/1*1.6093km=225.302km
Therefore the 140 miles in km is 225.302km
Assume your line starts at zero, your first point is (-3,5) meaning your have a slope of 5/-3
[ f(x) = 5/-3x + b]
First you have to get the number on the right 40 to equal 100 so do 40x2=80- +40x1.5= 100
Then do the same thing to the first number 8 so 8x2=16+8x1.5=20
then you have 20/100 right so then that number over 100 is the percent that you get ^-^ 20%
** x + 5 = 7
x = 2
** x + 5 = 9
x = 4
{2,4}
