Estimate the solutions to the system. (The math problem is in the pictures along with the answer choices)

Without graphing the linear functions, find the coordinates of the point of intersection of their graphs: y=3x−11 and y=4

Find an equation of the line perpendicular to the graph of 28x-7y=9 that passes through the point at (4,1)

Given the system of equations presented here: 2x + 4y = 14 4x + y = 20 which of the following actions creates an equivalent system such that, when combined with the other equation, one of the variables is eliminated? multiply the second equation by â’4 to get â’16x â’ 4y = â’80 multiply the second equation by â’1 to get â’4x â’ y = â’20 multiply the first equation by 2 to get 4x + 8y = 28 multiply the first equation by â’1 to get â’2x â’ 4y = â’14
