Choose the equation that represents a line that passes through points (−1, 2) and (3, 1). A: 4x − y = −6
B: x + 4y = 7
C: x − 4y = −9
D: 4x + y = 2

Asystem of equations has 1 solution. if 4x-y=5 is one of the equations , which could be the other equation ?

Complete the solution of the equation. find the value of y when x equals to 28 x+3y=28
