Choose the system of equations that matches the following graph:
the graph is a coordinate plane with line y equals negative 5 halves x minus 7 and line y equals 7x minus 7. they intersect at 0, negative 7
answer options:
a. 5x + 2y = −14
7x + y = 7
b. 5x + 2y = −14
7x − y = 7
c. 5x − 2y = −14
7x + y = 7
d. 5x − 2y = −14
7x − y = 7
