to find the x int, sub in 0 for y and solve for x
3x - 9y = 10.8
3x - 9(0) = 10.8
3x = 10.8
x = 10.8/3
x = 3.6 or (3.6,0) <== ur x int

to find the y int, sub in 0 for x and solve for y
3x - 9y = 10.8
3(0) - 9y = 10.8
-9y = 10.8
y = -10.8/9
y = - 1.2 or (0,-1.2) <== ur y int

The x-intercept and the y-intercept of the line described by the equation 3x - 9y = 10.8 are 3.6 and -1.2

The x-intercept of a line is the point where y-coordinate is zero while the y-intercept of the line is the point where the x-coordinate is zero

Given the expression 3x - 9y = 10.8

Get the x-intercept. If y = 0

3x - 9(0) = 10.8

3x = 10.8

x = 10.8/3

x = 3.6

Get the y-intercept. If x = 0

3(0) - 9y = 10.8

-9y = 10.8

y = -10.8/9

y = -1.2

Hence the x-intercept and the y-intercept of the line described by the equation 3x - 9y = 10.8 are 3.6 and -1.2
