(3,-1)
Use the V.L.T (Vertical Line Test) and plot the graph points, if you can draw a straight line through any points it cannot be a function.
We assume a linear system with 2 variables.
If the slopes are the same, and y-intercepts are different, there are 0 solutions.
If the slopes are different, there is 1 solution.
If the slopes are the same, and the y-intercepts are the same, there are ∞ solutions.
Answer:
The answer is 1 5/12.
Step-by-step explanation:
-12 + 8 - (-9) = 5
Therefore the value of -12 + 8 - (-9) is 5.
1 and 2 both have 1/4th slope, (2 is y=.25x +2.8)
3 has 1/4th slope, (y = 1/4x - 8/5)
4 has a -1/4th slope.
H would be correct as all the others have a 1/4th slope and IV is only one with a -1/4th slope
