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

How do we find the equation of a line?
Find the slope first, introduce x and y.
$$(y_2-y_1)/(x_2-x_1)$$
$$(y+2)=slope \times (x-2)$$

ya im still lost

anonymous · Answer

Joel, find the slope, then rearrange by keeping the x and y on one side.

anonymous · Answer

$$slope = (12-(-2))/(-5-2)$$
Now your equation will be the answer you get above times (x-2)=(y+2)

anonymous · Answer

if you're still lost try just plugging in those points into each equation and see which one holds true...
