line m is graphed below the line of the equation y=-1/3x+3 will be graphed with line m. what will be the point of intersection of the two lines

Respuesta :

The point of intersection of the two lines is (9/7,18/7)

How to determine the point of intersection

The equation of line m is given as:

[tex]y = 2x[/tex]

The second equation is given as:

[tex]y = -\frac 13x + 3[/tex]

Substitute 2x for y in the above equation

[tex]2x = -\frac 13x + 3[/tex]

Collect like terms

[tex]2x +\frac 13x = 3[/tex]

Multiply through by 3

[tex]6x +x = 9[/tex]

[tex]7x = 9[/tex]

Solve for x

[tex]x = \frac 97[/tex]

Substitute 9/7 for x in [tex]y = 2x[/tex]

[tex]y = 2\times \frac 97[/tex]

[tex]y = \frac {18}7[/tex]

Hence, the point of intersection of the two lines is (9/7,18/7)
