Solving Systems of Linear Equations: Graphing Answers

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).

What is the solution to the system of equations?2x – y = 7y = 2x + 3

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

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

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)

y=–6x+2–12x – 2y=–4

A coordinate grid with a line labeled y equals StartFraction 2 over 5 EndFraction x minus 5 passing through the points (negative 5, negative 7) and (0, negative 5)

Which values of m and b will create a system of equations with no solution? Select two options.y = mx + b y = –2x + m = –3 and b = m = –2 and b = m = 2 and b = m = and b = m = -2 and b =

A coordinate grid with 2 lines. The first line labeled f(x) passes through (negative 3, 3), (0, 2), and (3, 1). The second line labeled g(x) passes through the points at (negative 3, 0) and (0, 2)
