Question

I need the answer for this question

Answer 1

`(-1)/(2)`

Explanation:

Rate of change =
`(Change in Y value)/(Change in X value)`

Pick any two sets of 'X' and 'Y' value

I chose (-4, 6) as
`(X_(1) ,Y_(1) )`and (12, -2) as
`(X_(2) ,Y_(2) )` :

Rate of change = Slope / Gradient of graph =
`(Y_(2) -Y_(1) )/(X_(2) - X_(1) )`

=
`(-2 - (6))/(12 - (-4))`

=
`(-2 - 6)/(12 + 4)`

=
`(-8)/(16)`

=
`(- 1)/(2)`
