x=-5,y=-6.
The LCM of 2x5y and 4x3y2 is 4x5x3y2 = 60xy2.
4x3y2 is one term. You need at least two terms to find something in common between them.
4x3y
4x^3y
The GCF of 12x and 20x to the fourth power is 4x
The general equation of a line through point (x0, y0) with gradient m is given by: y - y0 = m(x - x0) The gradient m between two points (x0, y0) and (yx1, y1) is given by: m = change_in_y/change_in_x = (y1 - y0)/(x1 - x0) → line through points (1, 5) and (3, 17) is given by: y - 5 = ((17 - 5)/(3 - 1))(x - 1) → y - 5 = (12/2)(x - 1) → y - 5 = 6(x - 1) → y - 5 = 6x - 6 → y = 6x - 1
