The perimeter of a triangle is the sum of the lengths of the three sides.If the three expressions in the question are in fact the lengths of thethree sides, then the perimeter is their sum.(7x + 9w) + (2x + 8y) + (2y + 5w) = 9x + 10y + 14w

Gradient = [2 - (-5)]/[(-3) - 5] = -7/8So equation is y - 2 = -7/8*[x - (-3)]or 8y - 16 = -7x - 21that is 7x + 8y + 5 = 0Gradient = [2 - (-5)]/[(-3) - 5] = -7/8So equation is y - 2 = -7/8*[x - (-3)]or 8y - 16 = -7x - 21that is 7x + 8y + 5 = 0Gradient = [2 - (-5)]/[(-3) - 5] = -7/8So equation is y - 2 = -7/8*[x - (-3)]or 8y - 16 = -7x - 21that is 7x + 8y + 5 = 0Gradient = [2 - (-5)]/[(-3) - 5] = -7/8So equation is y - 2 = -7/8*[x - (-3)]or 8y - 16 = -7x - 21that is 7x + 8y + 5 = 0

4x + y = 9 so that y = 9 - 4x 7x - 8y = 6 7x - 8*(9-4x) = 6 7x - 72 + 32x = 6 39x = 78 x = 2 Then y = 9 - 4x = 9-4*2 = 9-8 = 1
