Answer:

The given system of equations will not have any solution.

Step-by-step explanation:

As shown in the graph attached,

2x + y = 2

y = -2x + 2

This line (red line) has the slope as (-2) and y-intercept as 2

Second line 4x + 2y = 9 graphed in blue line when divided by 2 it becomes

2x + y = 9

y = -2x + 4.5

This line has the slope (-2) and y-intercept 4.5.

Slope of both the lines are same as (-2) which shows that both the lines are parallel.

Since parallel lines don't have any solution, therefore, the given system of equations will not have any solution.

Step-by-step explanation:

Given,

Draw the graphs of the equations 2x+y=22x+y=2 and 4x+2y=94x+2y=9

First equation,

2x+y=22x+y=2

⇒y=-2x+2y=−2x+2

In this line has the slope as -2−2 and y-y− intercept as 22

Second equation,

4x+2y=94x+2y=9

⇒2y=-4x+92y=−4x+9

⇒y=-2x+\frac{9}{2}y=−2x+

2

9

In this line has the slope as -2−2 and y-y− intercept as \frac{9}{2}

2

9

This two line has same slope as -2−2

So, Both line are parallel.

Parallel line have no solution.

∴ Given two equation have no solution.
