Question

what is the equation in the point-slope from the line passing through (0 2) and (1 5)

a) y-5=3(x-1)
b) y-2=-3(x-0)
c) y+2=3(x+1)
d) y+5=-3(x+1)

Answer 1

\[\frac {y-5}{5-2}=\frac {x-1}{1-0}\]\[\frac {y-5}{3}=x-1\]y-5=3(x-1)

Answer 2

and the other one please ....

a) 2x-y=5
b) 2y-y=-5
c)2x+y=5
d) 2x+y=-5
