A system of equations has 1 solution. If 4x - y = 5 is one of the equations, which could be the other equation?
2 answers:
Answer:
y = -4x+5
Step-by-step explanation:
I graphed the given equation on the graph below and graphed the choices with it. Only one choice had one solution with the given equation. This equation is y = -4x+5
Answer:
O y=-4x + 5
Step-by-step explanation:
I graphed "4x - y = 5" and the other options using a graphing tool. After graphing, we can see:
"4x - y = 5" and " -2y = -8x - 10" has no solution. The lines are parallel.
"y = 4x-5" and "2y = 8x - 10" overlap over "4x - y = 5". They have an infinite number of solutions.
"y=-4x + 5" and "4x - y = 5" cross at point (1.25, 0). This means that they have one solution.
"y=-4x + 5" should be the correct answer.
