Question 682546
The way to find intercepts is:
x-intercept:
Set y = 0 and solve for x
---------------------
y-intercept:
Set x = 0 and solve for y
---------------------
{{{ 2x - 4 = y }}}
x-intercept:
Set y = 0 
{{{ 2x - 4 = 0 }}}
{{{ 2x = 4 }}}
{{{ x = 2 }}}
---------------------
y-intercept:
Set x = 0 
{{{ 2*0 - 4 = y }}}
{{{ y = -4 }}}
--------------
So, now you have 2 points you can plot:
(2,0) and (0,-4)
Here's the plot:
{{{ graph( 400, 400, -10, 10, -10, 10, 2x - 4 ) }}}
