Draw the graphs of the equations x + y = 6 and 2x + 3y = 16 on the same graph paper. Find the coordinates of the points where the two lines intersect
x | 0 | 2 | 6 |
y | 6 | 4 | 0 |
and 2x + 3y = 16
x | 2 | 5 | 8 |
y | 4 | 2 | 0 |
GRAPH:
So, from the graph we see that the two lines intersect at (2, 4).
