To find the x-int change the equation to standard form Ax+By=C
y=1/2x+6 subtract 1/2x from both sides.
-1/2x + y= 6 Multiply both sides by 2 to get rid of the fraction.
2( -1/2x + y)= 6(2)
-x + 2y = 12 Plug in 0 for y to find the x-int
-x + 2(0) = 12
-x = 12 Divide both sides by -1
x= -12
The x-int is (-12, 0)

where ever the line crosses the x axis so if you go on desmos.com and type the equation in you'll find it really easy. it crosses at (-12,0)
