2-20.

Examine the graph at below. .

1. In $(x,y)$ form, name the coordinates of points $A, B, C$, and $D$.

Find the change in $x$ and $y$ from the point $(0,0)$.

Point $A$ goes to the left $4$ spaces and up $3$ spaces. How do you write that in $(x,y)$ form?

$A$ is $(−4,3)$. Now find points $B, C,$ and $D$.

2. On graph paper, draw a set of axes like the ones shown above. Then plot points $E(5,2)$, $F(−3,−1)$, $G(0,−4)$, and $H(2,−3)$.

Use the eTool below to input the points into the table and graph the results.
