Question 157104: the problem says to graph these two equations on the same graph & then find where they intercept. There are more questions to the problem, but I think I can figure them out if I first get the graph correct.
Equations: 1) y=5x
2) y=3x + 100

Hi, Hope I can help,
.
the problem says to graph these two equations on the same graph & then find where they intercept. There are more questions to the problem, but I think I can figure them out if I first get the graph correct.
Equations: 1) y=5x
2) y=3x + 100
.
Here are the graphs of the two lines together
.
+y=5x+ (brown line)
.
+y+=+3x%2B100+ ( green line)
.

.
Here is the graph but smaller
.

.
The two lines intersect at point (50,250)
.
You can check by replacing "x" with "50", "y" with "250" in our two equations
.
+y=5x+ = +%28250%29+=+5%2850%29+ = +250+=+250+ (True)
.
+y+=+3x%2B100+ = +%28250%29+=+3%2850%29%2B100+ = +250+=+150%2B100+ = +250+=+250+ (True)
.
The lines intersect at point (50,250)(There are other ways of solving the intersection of two lines)(we knew the answer by the graph)
.
Hope I helped, Levi
