Determine the coordinates of each point of intersection without graphing. Homework Help ✎
y = 2x − 3
y = 4x + 1
y = 2x − 5
y = −4x −2
Use the Equal Values Method.
Set both equations equal to each other.
2x − 3 = 4x + 1
Get all the x terms on one side of the equation.
−2x = 4
Divide both sides by −2 to solve for x.
x = −2
Substitute this value into one of the original equations to solve for y.
Follow the steps in part (a).
