(0,0),(-1,2)
slope = (2 - 0) / (-1 - 0) = - 2/1 = -2
so this equation, since it goes thru the origin, is : y = -2x or 2x + y = 0
(2,3),(1,-2)
slope = (-2 - 3) / (1 - 2) = -5/-1 = 5
y = mx + b
slope(m) = 5
(2,3)...x = 2 and y = 3
now sub into the formula and find b, the y int
3 = 5(2) + b
3 = 10 + b
3 - 10 = b
-7 = b
so this equation is : y = 5x - 7 or 5x - y = 7
so ur 2 equations are :
2x + y = 0
5x - y = 7
