What equation I don't see one here
You would half to take 8×(8×pi r squared)
The y intercept = -4
Also, the slope of the line (if needed) is -2.
Y = 3...I believe in standard form, this would be written as : y = 0x + 3
y = an integer is a horizontal line...and if u have x = an integer, it would be a vertical line
