Question

What is the rate of change of y= -2x-1

Answer 1

The rate of change is -2

Step-by-step explanation:

The slope-intercept form of a linear equation is y = m x + b, where

• m is the slope which represents the rate of change
• b is the y-intercept which represent the initial value (value y at x = 0)

∵ y = -2x - 1

- The equation in the slope-intersect form, compare it with

    the form above

∴ m = -2

∴ b = -1

∵ m represents the rate of change

∴ The rate of change is -2

∵ b represents y at x = 0

∴ The y-intercept is -1

The rate of change is -2
