Solve the system by graphing y=-4x-2 -2x+y=-2 Plot both lines and point of intersection by moving the dots to the correct locati

UkoKoshka [18]

Answer:

The point of intersection is (0,-2).

Step-by-step explanation:

Equation 1: $y=-4x-2$

Equation 2 : $-2x+y=-2$

Plot the lines on the graph

Refer the attached figure

Equation 1: $y=-4x-2 ---- Red$

Equation 2 : $-2x+y=-2 ---- Blue$

Point of intersection : A point where both the lines intersect is called point of intersection.

So, Both lines intersect at point (0,-2)

So, Point of intersection is (0,-2)

Hence The point of intersection is (0,-2).
