I need to find an equation of the line containing the given pair of points (3,4) and (9,9). I have figured out that the slope is 5/6 but I can not figure out the b of y=5/6+b.

Best ResponseYou've already chosen the best response.0First of all, it's 5/6x +b Second, use pointslope form to get the answer : y  y1 = m(xx1) y9 = 5/6*(x9) y = 5/6x + 1.5

Best ResponseYou've already chosen the best response.0instead try this: given points: (x1,y1) and (x2,y2) (xx1)/(x2x1)=(yy1)/(y2y1) substituting, (x3)/(93)=(y4)/(94) (x3)/6=(y4)/5 5x15=6y24 5x6y+9 is the equation of the line u can check it. the slope calculated from this equation is same as the one u calculated
