How To: Rig a fly line

In this tutorial we learn how to rig a fly line. Start by preparing the floating line or sinking line to accept the fly. Carefully unwind your leader, then fasten it over the perfection loop and thread it through the fly line perfection loop. This should make a nice tight knot so you have a nice tight fly. When finished, you can remove the leader then coil it back up and make three loops and save for use later on. It's also smart to carry a pack of weighters in your vest so you can throw them...

How To: Write and graph an equation in slope intercept form

This video teaches us the method to write an equation in slope intercept form and to graph it. The equation of line is y = mx + c. m is the slope and c is the y intercept or the point where it crosses the y axis. Let us find the equation of line if it crosses (8,6) and m=1/2. Substituting the values of x,y and m we get 6=(8)(1/2)+b. Simplifying we get b=2. Substituting the values in the equation of line, we get y = m/2 + 2. Suppose we want to find the x coordinate of a point on the line given...

How To: Draw Eeyore from Winnie the Pooh

The user demonstrates how to draw Disney's Eeyore in this video. The first step is to draw a circle about the size of a 50 cent piece for his head and add construction lines to it, including one across the lower part of the circle to use as a reference. The user also suggests creating a mark below the "head" to mark where the end of Eeyore's jaw will be. Then, starting at the bottom cross line, he begins drawing the rounded area of his snout. Next, he draws a straight line from the other side...

Add smile lines on each side and draw a curve between them for the mouth. Extend the lower part of the mouth outside the construction line. Insert teeth and...

How To: Determine if a point lies on a line in slope intercept

In this video the author shows how to find out if a Point lies on a Line in Slope Intercept Form. He shows it by an example where he takes a point, which is an ordered pair in the form (x, y) and a line, which is an first degree equation. Now he substitutes the values of x and y in the equation and checks if both the sides of the equation match. If it matches we can conclude that the point lies on the line. By following the method given in this tutorial you can find out if a given point lies ...
