Question

Using the given points, determine Δy.

(-3, -5) and (0, 10)

Δy = 3
Δy = 5
Δy = 13
Δy = 15

Answer 1

\[\Delta y = y_2 - y_1\]

Answer 2

thanks

Answer 3

Np

Answer 4

This is essentially working up towards the slope formula which is \[m = \frac{ \Delta y }{ \Delta x } = \frac{ y_2-y_1 }{ x_2-x_1 }\]
