Step-by-step explanation:
Geometry is everywhere. Angles, shapes, lines, line segments, curves,<span> and other aspects of geometry are every single place you look. Letters themselves are constructed of lines, line segments, and curves.</span>
If a graph is proportional then the line will go through the origin at point (0, 0). If the equation is proportional then it will be in the form of y=kx with no other operations after. The constant of proportionality is another way to say the slope and in your specific equation the slope would be 1/5.
36 miles per hour if he ran 12 miles in 20 minuets and there are 60 minuets in an hour, then multiply the # by 3
