Question 932912
8x+4y=-24
x = 0 , y-intercept = -6
y = 0,  x-intercept = -3
.....
the standard slope-intercept form for an equation of a line is 
{{{y = highlight_green(m)x + highlight(b)}}}  where m is the slope and b the y-intercept.  
8x+4y=-24
0r
y = -2x - 6
-2 is the slope and -6 the y-intercept.  
Plot intercepts and connect with line (slants to the left...negative slope)
