Graph. x+y<-1 I know I have to subtract the x and make it to y<-x+1 but how do I get the coordinates to plot and graph it.?
x + y < -1
subtract x from both sides to get...
y < -1 - x
now create a t-chart for x and y coordinates. pick numbers for x and substitute them into the inequality to find the value of y
0 -1 - 0 = -1
1 -1 - 1 = -2
2 -1 - 2 = -3
so three coordinates are (0, -1), (1, -2), and (2, -3)
graph these points and connect with a dashed line because the symbol is < not =
finally shade below the line (because it is less than)
the bottom left side of the graph would be shaded
