Answer:
x - intercept : (27,0)
y- intercept : (0,81)
Step-by-step explanation:

you can rearrange the right side to make the equation look like y=mx+b

According to y=mx+b, b is the y-intercept
∴ (0,81) is the y-intercept of the equation
To find the x-intercept, plug in 0 for y and solve for x

∴ (27,0) is the x-intercept of the equation
