A line has a slope of 3 and includes the points (9, -3) and (10, t). What is the value of t?
t =

t=0

Step-by-step explanation:

if the slope is 3 the y coordinate with increase by 3 every time the x coordinate goes up 1. So when the x coordinate goes up 1 from 9 to 10, the y coordinate goes up 3 from -3 to 0.

  (-3, -6)

Step-by-step explanation:

The scale factor multiplies each coordinate.

  A' = 3A = 3(-1, -2) = (-3, -6)

The image of A is ...

  A'(-3, -6)
