hypotenuse
the two vertical and horizontal "legs" of a triangle. the other diagonal line is the hypotenuse.
right triangle
Draw a straight line from the intercept to the given point. Under this line form a right angle triangle with the line being its hypotenuse. The vertical units of the triangle divided by the horizontal units will be the slope of the straight line.
a^2 + b^2 = c^2 a theorem to find the length of sides of right triangles a = ( generally ) the Y, vertical side of the triangle b = ( generally ) the X, horizontal side of the triangle c = the hypotenuse of the triangle; the side opposite the 90 degree angle

right triangle
Larger by a factor of √2. If you draw a vector at 45°, then draw a vertical line from the end of that vector, you have a 45° right triangle. If you recall your trig. relationships, the hypotenuse of a 45° right triangle is √2 (or 1.414) times the length of either leg.
Draw a straight line from the intercept to the given point. Under this line form a right angle triangle with the line being its hypotenuse. The vertical units of the triangle divided by the horizontal units will be the slope of the straight line.

Draw a line of best fit through the plotted points which will give the y intercept. Draw a right angle triangle under the line which will be the triangles hypotenuse. Divide the vertical units of the triangle by the horizontal units which will give the value of the slope.
a square
It is equal to 1 (one). A 45 degree angle produces a vertical rise equal to the horizontal run, producing an isosceles right triangle with a hypotenuse of (sq rt 2)*a where a is the height/side. Opposite over adjacent = a/a = 1.
Vertical is up and horizontal is across
