Question 920053
x y 
–3 7 
 -2 5 m ={{{(y[1] - y[2])/(x[1] - x[2] )}}} = 2/-1 = -2
y - 5 = (-2)(x+2)
y = -2x + 1
........
 Line 2 
 x y 
 0, 5 
 2, 1 m ={{{(y[1] - y[2])/(x[1] - x[2] )}}} = 4/-2 = -2
y - 5= (-2)(x-0)
y = -2x + 5
Same Slope. y-intercept of Line1 = 1 and Intercept of Line2 = 5.
 Lines are Parallel.  NO Solution
