4-93.

Determine the coordinates of each point of intersection without graphing. Homework Help ✎

*y*= 2*x*− 3*y*= 4*x*+ 1*y*= 2*x*− 5*y*= −4*x*− 2

Use the Equal Values Method.

Subtract 2*x* from both sides.

Subtract 1 from both sides.

Divide by 2 on both sides.

*y* = *y*

2*x* − 3 = 4*x* + 1

−3 = 2*x* + 1

−4 = 2*x*

(−2, −7)

Follow the hints and steps used in part (a).

Use the value you found for *x* and substitute into one of the original equations to solve for *y*.
