Math·Algebra·Systems of two linear equations in two variables
mediumThe graph of a system of two linear equations is shown in the xy-plane. One line passes through the points (0,−2) and (9,−3), and the other line passes through the point (0,2) with a steep positive slope. Which of the following systems of equations is represented by the graph?
A
y = 9x + 2
y = -1/9x - 2
y = -1/9x - 2
B
y = 2x + 9
y = -2x - 9
y = -2x - 9
C
y = 1/9x + 9
y = 1/9x - 9
y = 1/9x - 9
D
y = 9x + 2
y = 9x - 2
y = 9x - 2
