To solve for the point of intersection using elimination, you first want to modify the equations so that one of the variable coefficients in both equations match. You have: 1. \(8x + 2y = -2\) (Equation 1) 2. \(y = -4x + 3\) (Equation 2 - from reformatting a similar equation). Now, let's multiply Equation 2 by 2 to align it with Equation 1: \[ 8x + 2y = 6 \] Now you have: - \(8x + 2y = -2\) (Equation 1) - \(8x + 2y = 6\) (Transformed Equation 2) Next, subtract Equation 1 from the transformed Equation 2: \[ 0 = 6 + 2 \] This leads to a contradiction, implying that there is no solution and the lines representing the equations do not intersect. Therefore, they are parallel. To sum up, when you perform elimination, always check if the manipulated equations give you a valid context or if they clarify the relationship between the equations. Always keep an eye out for parallel lines; they signal no intersection!
