Mathematics

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

What is an equation of the line in the slope- intersepct is (0,3)
balu736 [363]

Answer:

using the formula x/a + y/b =1

a: slope intercept on the x axis

b:slope intersect on the y axis

x/0 + y/3 = 1 (since x/0 is undefined ,the slope doesn't exist and it is impossible for a slope to be linear)
