Question

Y = -2x - 5

6x + 3y = -15



A.one line


B.parallel lines


C.intersecting lines

Answer 1

A. One line

Explanation:

Let rearrange the system of equations into explicit forms:

`y = -2\cdot x - 5`

`6\cdot x + 3\cdot y = -15`

`3\cdot y = -6\cdot x - 15`

`y = -2\cdot x - 5`

The second equation is identical to the first one, which means that there is just one line.
