Question

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

t =

Answer 1

t=0

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.
