Which system of equations does NOT have the same solution as the system below? 3 x + 5 y = 10 3x\ +\ 5y\ =10 3 x + 5 y = 1 0 − x + 4 y = − 3 -x\ +4y\ =-3 − x + 4 y = − 3

6 x + 10 y = 20 6x\ +\ 10y\ =\ 20 6 x + 1 0 y = 2 0 − 3 x + 12 y = − 3 -3x\ +12y\ =-3 − 3 x + 1 2 y = − 3

30 x + 50 y = 100 30x\ +50\ y\ =100 3 0 x + 5 0 y = 1 0 0 − 10 x + 40 y = − 30 -10x\ +\ 40y\ =-30 − 1 0 x + 4 0 y = − 3 0

18 x + 30 y = 60 18x\ +30y\ =60 1 8 x + 3 0 y = 6 0 − 6 x + 24 y = − 18 -6x\ +24y\ =-18 − 6 x + 2 4 y = − 1 8

− 15 x − 25 y = − 50 -15x\ -25y\ =\ -50 − 1 5 x − 2 5 y = − 5 0 − 1 2 x + 2 y = − 3 2 -\frac{1}{2}x+2y\ =-\frac{3}{2} − 2 1 x + 2 y = − 2 3

How do we know if a system of equations has no solution?

The lines are not in slope-intercept form (y=mx+b)

The lines have the same slope and y-intercept

Which of these systems has an infinite number of solutions?

y = 3 x + 4 y=3x+4 y = 3 x + 4 − 12 x + 4 y = 16 -12x+4y=16 − 1 2 x + 4 y = 1 6

y = − 2 x + 1 y=-2x+1 y = − 2 x + 1 y = − 2 x − 3 y=-2x-3 y = − 2 x − 3

x + 2 y = 10 x+2y=10 x + 2 y = 1 0 2 x + 4 y = 10 2x+4y=10 2 x + 4 y = 1 0

y = 2 x + 6 y=2x+6 y = 2 x + 6 4 x − 2 y = 8 4x-2y=8 4 x − 2 y = 8

Is (-1,5) a solution to this system of equations?

x + y = 4 x+y=4 x + y = 4 x = − 1 x=-1 x = − 1

y = − x + 4 y=-x+4 y = − x + 4 y = − 1 5 x y=-\frac{1}{5}x y = − 5 1 x

y = 5 y=5 y = 5 y = x − 6 y=x-6 y = x − 6

y = x + 6 y=x+6 y = x + 6 x = 2 y + 7 x=2y+7 x = 2 y + 7

Graphically, the pair of equations 6x – 3y + 10 = 0 , 2x – y + 9 = 0 represents two lines which are

intersecting at exactly one point

intersecting at exactly two points.
