Question 340152
What are the intercepts from x + y = 56?
x-int: Let y=0. Then x = 56
y-int: Let x=0. Then y = 56
--------------------------------------------
What are the intercepts from 3y + x = 56?
x-int: Let y=0. Then x = 56
y-int: Let x=0. Then 56/3
------------------------------
Where would the lines intersect on a graph?
y = -x+56
y = (-1/3)x+(56/3)
-------------
Solve for "x":
-x+56 = (-1/3)x+(56/3)
-3x+168 = -x+56
2x = 112
x = 56
If x = 56, y = 0
========================
Graph:
{{{graph(400,300,-10,60,-10,60,-x+56,(-1/3)x+(56/3))}}}
