The slope of the graph is:




So, the graph equation is:




In standard form, we have:

Answer:

Step-by-step explanation:

and
are equal, we can set them equal to each other:

Substitute
to solve for
:

3:5=x:50
Therefore 5 ×x = 50
x = 10
Therefore 3 × 10 = 30
therefore 30 blue pens
proof = 30 blue + 50 red= 3+ 5
therefore 80 = 8x
