Q. Find the x-intercept of the line 3x+20y=−12. Write your answer as an integer or as a simplified proper or improper fraction, not as an ordered pair.
Set y to 0: To find the x-intercept, we set y to 0 and solve for x.Substitute 0 for y in 3x+20y=−12.3x+20(0)=−123x=−12
Substitute y with 0: Now, divide both sides by 3 to solve for x.33x=3−12x=−4
