You can put this solution on YOUR website! Describe how you can use the equations y=5x and y=3x+100 to find when the two points of the equations will meet on the graph:
:
solve for x and y:
substitute 5x for y in the 2nd equation, find x:
5x = 3x + 100
5x - 3x = 100
2x = 100
x =
x = 50
:
Find y
y = 5x
y = 5(50)
y = 250
;
graphs will meet at x/y coordinates: 50,250
