    to get the equation of a line you do y-y1=m(x-x1) y1 is a y coordinate x1 is an x coordinate

    find slope first (y1-y2) / (x1-x2) so it is (-6 - (-1)) / (-2 - 4) = 5/6 y = mx + b y= 5/6x + b -1 = 5/6(4) + b solvve for b b = -26/6 eq: y= 5/6x -26/6

    doesnt matter you get slope either way y1 and y2 is to show these are 2 different numbers at 2 different points
