Question 503726
You need to find
(x,0) ( the x-intercept ) and
(0,y) ( the y-intercept )
First, (x,0):
{{{ 8x + 7y = -5 }}}
{{{ 8x + 7*0 = -5 }}}
{{{ 8x = -5 }}}
{{{ x = -(5/8) }}} is the x-intercept
and, (0,y):
{{{ 8*0 + 7y = -5 }}}
{{{ 7y = -5 }}}
{{{ y = -(5/7) }}} is the y-intercept
--------------
Here's the plot:
{{{ graph( 400, 400, -4, 4, -4, 4, -(8/7)*x - 5/7) }}}
