Question

State the value of m and the value of b!

A. F(x):m= , b=
B. G(x): m= , b =
C. H(x): m = , b=

Answer 1

A) f(x) goes down 1 for each 2 it goes to the right, so its slope is m = -1/2. It crosses the y-axis at b = 2.

B) g(x) goes up 1 for each 3 it goes to the right, so its slope is m = 1/3. It crosses the y-axis at b = -3.

C) h(x) goes up 2 for each 1 it goes to the right, so its slope is m = 2/1 = 2. It crosses the y-axis at b = 0.
