Answer:
The intercepts 
Step-by-step explanation:
Given:

Required
Determine the intercepts
The equation is a linear equation and the intercepts of the equation is calculated as thus;
For x intercepts; substitute 0 for y




Add 1 to both sides


Divide both sides by 4


Simplify fraction to lowest term

For y intercept, substitute 0 for x




Subtract 5 from both sides


Divide both sides by 3


Reorder

Hence, the intercepts
