consider the linear equation
9x-2y=18
find the y intercept and x intercept
Y-intercept:
Let x = 0, then y = -9
(A) ( 0,-9 )
--------
X-intercept:
Let y = 0, then x = 2
(B) ( 2 , 0 )

The -coordinate of the -intercept is zero, and the -coordinate of the -intercept is zero. So substitute 0 for in the equation and solve for the -coordinate of the -intercept. Then substitute 0 for in the equation and solve for the -coordinate of the -intercept.

if you put it in the form ,
then is the y-intercept

Add to both sides

Subtract from both sides

Divide both sides by

So, the y-intercept is at (0,-9)
-------------------------
To find the x-intercept, set



The x-intercept is at (-2,0)
