Solving Systems of Linear Equations: Graphing Answers

What value of b will make the system of equations have an infinite number of solutions?y = -2x + b 4x + 2y = 8

A system of equations has no solution. If y = 8x + 7 is one of the equations, which could be the other equation?

Sylvie finds the solution to the system of equations by graphing.y = x + 1 and y = x – 1Which graph shows the solution to Sylvie’s system of equations?

What value of b will cause the system to have an infinite number of solutions?

Raphael graphed the system of equations shown.y = – 3y = x – 0.8What is the best approximation for the solution to this system of equations?

A coordinate grid with one line labeled y equals 3 x plus StartFraction 3 over 4 EndFraction. The line passes through points at (negative 1, negative 2) and (0, 1).

A coordinate grid with 2 lines. The first line is labeled y equals negative StartFraction 7 over 4 EndFraction x plus StartFraction 5 over 2 EndFraction and passes through the (0, 2.5) and (2.2, negative 1.4). The second line is labeled y equals StartFraction 3 over 4 EndFraction x minus 3 and passes through (0, negative 3, 0.14) and (2.2, negative 1.4)

How many solutions does this linear system have?y = 2x – 5 –8x – 4y = –20

Billy graphed the system of linear equations to find an approximate solution.y = x + y = x – 3Which points are possible approximations for this system? Select two options.(1.9, 2.5)(2.2, –1.4)(2.2, –1.35)(1.9, 2.2)(1.9, 1.5)
