First: replace "0" with the y-variable...
5x - 3(0) = 9
5x - 0 = 9
5x = 9
Sec: isolate "x" on one side > divide both terms by "5"...
5x/5 = 9/5
x = 9/5
>>> (9/5, 0)
The x-intercept is a point that lies on the x-axis.

In the case of x intercept the value of y will be zero.
So if we put y=0 in the given equation we will get 5x=9
so, x=9/5=1.8

It is the location where the line intersects the x-axis.
By definition, at the x-axis, y=0.
Thus when y=0, find that x=9/5
Thus the x-intercept is the coordinate, (x,y) (9/5,0)

add -3y to the right side of the 9. put it first. so now you have
5x =-3y-9. divide by 5. can you take it from there?

first solve for y and put it into slope-intercept (y=-5/3x-3) then put a 0 in for y and solve for x (9/5)

5x-3(0)=9
x=9/5

this is where y=0
so 5x-3(0)=9
5x=9
x-9/5 or 1.8

are you making us do your homework? Read the directions...you have to set one variable equal to zero then solve for the other...its not that hard.
For x-intercept, set y=0
For y-intercept, set x=0

umm. im thinkin its y= -5/3x-3
x intercept is -5/3.
iono tho, i did it all in my head
