Question

Examine the system of equations. Do you think the lines will intersect? Explain.

Answer 1

Answer:

Step-by-step explanation:

Sample Response/Explanation: Yes, the lines will intersect because the slopes are different. Also, both lines have a y-intercept of -7, so they both include the point (0, –7).

Which did you include in your response? Check all that apply.

The lines will intersect.

The slopes are different.

The point (0, –7) lies on both lines.

Answer 2

Yep they do, because if you plug in y for both equations, you get x=0. To find y, plug in 0 for either equation to get -7.  (0,-7) should work for both equations since the intersection point is the point where both equations meet.
