Question

how do you graph 2x+y+2=0?

Answer 1

you can do it this way:-
write it in slope-intercept form
y = mx + c where m = slope of the line and c is intercept on y-axis
so that's
y = -2x - 2

Answer 2

find the y intercept by plugging in x = 0 and finding y
the slope is -2 . Note that negative slopes are like this: \
