Which graph shows a system of equations with a solution at 2 comma negative 1 ?
Answer
A
Image with description On a coordinate plane, the scale on the x and the y axes ranges from negative 5 to 5 in increments of 1. A parabola opens down and has the vertex at 0 comma 1. A straight line has a positive slope, passing through the points 0 comma negative 3 and 3 comma 0.
B
Image with description On a coordinate plane, the scale on the x and the y axes ranges from negative 5 to 5 in increments of 1. A parabola opens up and has a vertex at 0 coma negative 3. A straight line has a negative slope, passes through the points negative 3 comma 0 and 0 comma negative 3
C
Image with description On a coordinate plane, the scale on the x and the y axes ranges from negative 5 to 5 in increments of 1. A parabola opens down and has a vertex at 0 comma 3. A straight line has a positive slope, passes through the points 1 comma 0 and 0 comma negative 1.
D
Image with description On a coordinate plane, the scale on the x and the y axes ranges from negative 5 to 5 in increments of 1. A parabola opens up and has a vertex at 0 coma negative 2. A straight line has a positive slope, passes through the points 1 comma 0 and 0 comma negative 1.
