Question 175926
(1) {{{4x + 5y = -2}}}
(2) {{{4y - x = 11}}}
Put (1) and (2) in the slope-intercept form {{{y = mx + b}}}
(1) {{{5y = -4x -2}}}
{{{y = -(4/5)x - 2}}}
and
(2) {{{4y - x = 11}}}
{{{4y = x + 11}}}
{{{y = (1/4)*x + (11/4)}}}
{{{ graph( 600, 600, -16, 3, -5, 5, -(4/5)*x - 2, (1/4)*x + 11/4) }}}
