Question

Identify the slope and y-intercept of the line with the given equation then graph the equation.

Y=-2

* must use slope-intercept form

Answer 1

Y = -2.

This is ihe Eq of a hor. line, and it is 2 units below the x-axis. Since y is
constant, it is = -2 for all values of x:

(x,y).
(-2,-2)
(0,-2)

m = (-2-(-2)) / (0-(-2)) = 0/2 = 0.

Y = mx + b = -2.
0*-2 + b = -2
b = -2. = y-Int.

Use the following points for graphing:

(-2,-2)
(0,-2)
(2,-2)
