To identify the x-intercept, we must put the equation is Standard Form.

Standard Form: Ax+By=C

Algebraic Solving:

-1/2x+y=1/2x-1/2x+3

•We must subtract 1/2x from both sides to cancel it out from the right and move it to the left.
——————————————————

-1/2x+y=3

•The equation is now in standard form: Ax+By=C.
——————————————————

To identify the x-intercept, we will substitute zero in for y because we want to find where the line crosses or intercepts the x-axis, not the y-axis.

Set y=0

-1/2x+y=3

-1/2x+(0)=3
—————————

-1/2x=3

-1/2x•-2/1=3•-2/1

• To cancel out a fraction, we use the reciprocal, meaning the fraction is just flipped. This cancels out fraction and leaves us with x.
———————————————————————

x=6/1

x=6.

Therefore, the line crosses the x-axis at (6, 0)
