Question

Find the rate of change

Answer 1

3rd option

Explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the rate of change and c the y- intercept )

Given

2x + 8y = - 4 ( subtract 2x from both sides )

8y = - 2x - 4 ( divide terms by 8 )

y = -
`(2)/(8)` x -
`(4)/(8)` , that is

y = -
`(1)/(4)` x -
`(1)/(2)` ← in slope- intercept form

with rate of change m = -
`(1)/(4)` and y- intercept c = -
`(1)/(2)`
