Question 782618
{{{ x/4 - y/7 = 1 }}}
Multiply both sides by {{{ 28 }}}
{{{ 7x - 4y = 28 }}}
The y-intercept is at ( 0,y )
The x-intercept is at ( x,0 )
-----------------------------
y-intercept:
{{{ 7*0 - 4y = 28 }}}
{{{ -4y = 28 }}}
{{{ y = -7 }}}
--------------
x-intercept:
{{{ 7x - 4*0 = 28 }}}
{{{ 7x = 28 }}}
{{{ x = 4 }}}
-------------
The y-intercept is at ( 0,-7 )
The x-intercept is at ( 4,0 )
here's the plot:
