y = x
3x = 5
−2x = 7y

Question

Which of the following equations is parallel to the line passing through A(−2, 7), B(−2, −2)?  (1 point)
y = −2
y = x
3x = 5
−2x = 7y

anonymous · Answer

y=-2
-2=-2
7=-2
y=x
7=-2
-2=-2
3x=5
3*-2=5
-6=5
3*-2=5
-6=5
-2x=7y
-2*-2=7*7
4=49
-2*-2=7*-2
4=-14
none of the choices work

anonymous · Answer

I didn't think they did either that's why I asked but these are the only choices I have!

austinl · Answer

You have two points on a line yes?
(-2,7) & (-2,-2)

To find the slope between the two lines we use,

$\displaystyle slope=\frac{rise}{run}=\frac{\Delta y}{\Delta x}=\frac{y_2-y_1}{x_2-x_1}$

Then we need to look for a line in those given that has the same slope, which means that the two lines are parallel.

I got -9/4 ..

austinl · Answer

you should get an x value of 0.

anonymous · Answer

so y=x is my answer?

austinl · Answer

I would think so, if you have a slope over zero, that means you have a vertical line.
