Question

What is an equation in point-slope form for (18, 26) and (20, 32)? What is the domain and range of the equation? Please explain the clearest and shortest way possible. Thanks!

Answer 1

slope = 32-26 / 20-18 = 3 = m
use
y-y1 = m(x-x1)
y-32 = 3(x-20)

is that point-slope form? (we don't use that naming convention in the uk)

Answer 2

Yeah.

Answer 3

there you go then
are you happy with that or do you need more explanaation
