Simple linear equation y = mx + b where m is the slope and b is the y intercept. Since m = dy/dx = [10-4]/[6-(-3)] = 6/9 = 2/3 and the y intercept is given by the coordinate 6,10 the answer is B : y=2/3x + 6

y=kx+m
k=(10-4)/(6-(-3))=2/3
y=2/3x+m
use (6,10) in this equation to get m
10=2/3*6+m
m=6
y=2/3x+6

B
It's just plug 'n play. If you're finding this difficult, you is gonna be in *real* trouble when you hit things like factoring. Maybe you should get a tutor.
