PLEASE ANSWER

x is the independent variable.

y is the dependent variable.

-3 is the rate of change (slope).

-7 is the initial value.

Step-by-step explanation:

The form of the linear relation is y = m x + b, where

  • m is the rate of change (slope)
  • b is the initial value(value of y at x = 0)
  • x is the independent variable
  • y is the dependent variable

∵ The equation of the line is y = -3 x - 7

- Compare it with the form above

∴ m = -3

∵ m is the rate of change

∴ The rate of change is -3

∴ b = -7

∵ b is the initial value

∴ The initial value is -7

∵ y depends on x

∴ x is the independent variable

∴ y is the dependent variable

x is the independent variable.

y is the dependent variable.

-3 is the rate of change (slope)

-7 is the initial value.
