Answer:

[tex]y=\frac{1}{4}x+1[/tex]

Step-by-step explanation:

the common formula of the required equation is:

[tex]\frac{x-X_A}{X_B-X_A} =\frac{y-Y_A}{Y_B-Y_A};[/tex]

if to substitute the given coordinates into the folmula above, then the required equation is:

[tex]\frac{x-0}{4-0} =\frac{y-1}{2-1};[/tex] ⇔ y-1=1/4*x; ⇔  [tex]y=\frac{1}{4} x+1.[/tex]
