Answer

$x$-intercept $=-3$ $y$-intercept: $=-2$

Work Step by Step

$2x+3y+6=0$ To find this equation's $x$-intercept, set $y$ equal to $0$ and solve for $x$: $2x+3y+6=0$ $2x+3(0)+6=0$ $2x+6=0$ $2x=-6$ $x=-\dfrac{6}{2}$ $x=-3$ To find this equation's $y$-intercept, set $x$ equal to $0$ and solve for $y$: $2x+3y+6=0$ $2(0)+3y+6=0$ $3y+6=0$ $3y=-6$ $y=-\dfrac{6}{3}$ $y=-2$ The intercepts of this equation are now known. The graph is shown below:
