## anonymous one year ago Help me please! :3 Using the given points, determine Δy. (-3, -5) and (0, 10) a) Δy = 3 b) Δy = 5 c) Δy = 13 d) Δy = 15

1. freckles

just find the difference of the y's

2. freckles

$\text{ Say we have points } (x_1,y_1) \text{ and } (x_2,y_2) \\ \text{ then } \Delta x=x_2-x_1 \text{ and } \Delta y=y_2-y_1$

4. freckles
