Question

Which equation represents the line passing through the points (2, −2) and (−5, 12)?

2x − y = 2

2x + y = 2

x + 2y = 2

x − 2y = 2

Answer 1

Can you find the slope ?

Answer 2

\[m=\frac{-2-12}{2-(-5)}=\frac{-14}{7}=-2\]

Answer 3

\[y-(-2)=-2(x-2), y+2=-2x+4, 2x+y=2\]

Answer 4

The second one.
