What is the graph of the inequality in the coordinate plane? y<-4
1 answer:
Hola Jessica!
Essentially it's a horizontal, dashed line crossing directly over the -4 in the y-axis.
Keep in mind stuff like y = h or y </>/≤/≥ h all result in horizontal lines with it crossing directly over h. x = v or x </>/≤/≥ v all result in vertical lines crossing directly over v.
< = dashed-line; shade above line
> = dashed-line; shade below line
≤ = solid-line; shade above line
≥ = solid-line; shade below line

Answer:
1. Create a table that has a column for x and a column for y.
2. Plugin values for x and solve for y using the equation.
<u>X | Y</u>
-2 | -1
-1 | 1
0 | 3
1 | 5
2 | 7
3. Plot these values on a coordinate plane to graph them.
