Line A passes through points (-1, 5) and (3, -1). Line B passes through points (7, 2) and (6, -1).
At what point does line A intersect line B?

Question

Line A passes through points (-1, 5) and (3, -1). Line B passes through points (7, 2) and (6, -1).
At what point does line A intersect line B?

anonymous · Answer

First, find the slope of each line. Then you can find the y= mx + b equations for line A and line B by plugging in one of the given points. After you have the equations for both lines, since they intersect at the same point, you can set the equations equal to each other and solve for the x-coordinate of the point of intersection.

Then plug in the x-coordinate to find the y-coordinate. 

The answer should be (3.44, 8.67)
