Can anyone find the x and y intercepts for this equation?

ASHA 777 [7]

1/3x - 1/2y = 1

At the 'x' intercept, y=0 , and the equation is 1/3 x = 1

Multiply each side by 3 : x = 3  <== the x-intercept

At the 'y' intercept, x=0, and the equation is -1/2 y = 1

Multiply each side by 2 : - y = 2

Multiply each side by -1 :  y = -2  <== the y-intercept
