Which equation represents the line passing through the points (2, -2) and (-5, 12)?
Answer
2x - y = 2
2x + y = 2
x + 2y = 2
x - 2y = 2

anonymous · Answer

you have two points and want the equation for the line. first you need to find the slope

anonymous · Answer

$$m=\frac{y_2-y_1}{x_2-x_1}=\frac{12-(-2)}{-5-2}=\frac{14}{-7}=-2$$

anonymous · Answer

now  we can use the point slope formula to find the equation of the line, or else we can recall that the slope of $ax+by=c$ is $-\frac{a}{b}$ and see which line works, since all your choices have different slopes

anonymous · Answer

only the second line has slope  $-2$ so that one is correct

anonymous · Answer

the second one is right?

anonymous · Answer

yes
