We have two points so we can make two point slope equations... The general point-slope form is y-y1=m(x-x1), where m=slope and (x1,y1) is any point on the line. Since all choices show a slope of 3 we will omit calculating the slope=(y2-y1)/(x2-x1). We have two points (1,13) and (-2,4) so y-13=3(x-1) and y-4=3(x+2) So the only valid answer is A
