The two of the laser beams are in a straight line and the location of the heated focal point is (3, 4)
How to find the location of the point
The heated located point is where the two lines intersect
From the graph, we can see that the location of the heated focal point represented by x + 1 = -x + 7 is (3, 4)
complete question
A machine heats up a single point by shining several lasers at it. The equations y=x+1 and y=-x+7 describe two of the laser beams. Graph both lines and describe the location of the heated focal point.
