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

Answer:
B
Step-by-step explanation:
This is a really simple topic. All you need to do when seeing these ordered pairs is see which has x-values that don't repeat. Over here, we can see that that is B, so B is the correct option.
Option B is not a solution.
5y=3x+15
5(12)=3(-15)+15
60=-45+15
60≠-30
