first thing u do is pick any 2 points (x,y) from ur table
(1,3) and (2,6) now we sub those into the slope formula (y2 - y1) / (x2 - x1) to find the slope (y2 - y1) / (x2 - x1) (1,3)....x1 = 1 and y1 = 3 (2,6)...x2 = 2 and y2 = 6 sub slope = (6 - 3) / (2 - 1) = 3/1 = 3
now we use slope intercept formula y = mx + b y = mx + b slope(m) = 3 use any point off ur table...(1,3)...x = 1 and y = 3 now we sub and find b, the y int 3 = 3(1) + b 3 = 3 + b 3 - 3 = b 0 = b
so ur equation is : y = 3x + 0....which can be written as y = 3x...and if u sub any of ur points into this equation, they should make the equation true....if they dont, then it is not correct
and if u need it in standard form.. y = 3x -3x + y = 0 3x - y = 0 ...this is standard form
