The two lines graphed below are not parallel. how many solutions are there to the system of equations?

one solution

Step-by-step explanation:

If we are given a pair of linear equations, we can graphically evaluate the number of solutions to them. The rules are explained below

a) Lines are intersecting : If the lines are plotted on graph and they are intersecting at one point they have one unique solution.

b) Lines are parallel : If lines when drawn on graph , they are not intersecting how much we stretch them. Hence they have no solution .

c) Lines are overlapping : If lines are overlapping on each other on graph that means that they have many solution. In fact every point lying on the line is the solution.

Hence the graph is showing that they are intersecting therefore they have unique solution.

( - 4 , -7 )

all the lines must parallel  

step-by-step explanation:

coordinates of c = ( - 1 , 2 )

3 units left = ( -4 , 2 )

9 units down = ( - 4 , 11 )
