Question

Forgot how to do this :/ Write an equation in point-slope form for a line.
a. slope 2; (4,3)
b. slope -2/3; (-6,7)
c. slope 0; (-4,4)

Answer 1

(y-y1)=m(x-x1)
that ring a bell? :)
y1,x1 are your points

Answer 2

Thanks!

Answer 3

Wait, would you maybe be able to do a. as an example? :/ Sorry, it'd help me though @Sheng

Answer 4

np, so say #1
y-3=2(x-4)
all i did was plug in slope, and coordinates
simplify now
y - 3 = 2x-8
y = 2x-5
