2-20.

Examine the graph at right. 2-20 HW eTool (Desmos)

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 at right.  Then plot points $E(5,2)$, $F(-3,-1)$, $G(0,-4)$, and $H(2,-3)$.

Use the points above and the graph above to plot points $E$, $F$, $G$, and $H$. Remember that the horizontal axis is the $x$-axis, and the vertical axis is the $y$-axis.
