How do I solve for n and m using special right triangle rules.

Because the triangle is a 45-45-90 triangle, the n and m should be the same lengths. For these types of triangles, the hypotenuse is and the side lengths are x. Because we are given the length of the hypotenuse, we need to find the x-value. The equation should be 6=. Simplify to get x=. So, the length of n and m should both be .

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
