GKT101: General Knowledge for Teachers – Math

1. A. Point A and D. Point D.

The $y$-coordinate is on the vertical axis.

Values above $0$ on the number line are greater than $0$.

The red line shows where $y=0$. Points above the line have a $y$-coordinate that is greater than $0$.

The points where the $y$-coordinate is greater than $0$ are point $A$ and point $B$.

2.

To get to point $A$ from origin $(0, 0)$, we move right to $0.5$ and up to $4$.

To get to point $B$ from origin $(0, 0)$, we move left to $-3$ and down to $0$.

To get to point $C$ from origin $(0, 0)$, we move left to $-1$ and up to $0$.

3.

To graph $\left(7 \frac{1}{2},-2\right)$, we move right $7 \frac{1}{2}$ from the origin $(0, 0)$, then down $2$ from there.

To graph $(-3, 7)$, we move left $3$ from the origin& $(0, 0)$, then up $7$ from there.

To graph $(2, 0 )$, we move right $2$ from origin  $(0, 0)$, then up $0$ from there.

$\left(7 \frac{1}{2},-2\right),(-3,7)$ and $(2,0)$ are graphed below.

4. D. $(-6, 5 )$

Let's label the graphed points.

$(6,−5)$ was not graphed.

5. A. $(6, 5 )$, C. $(5, -6 )$, and D. $(6, -5 )$

The $y$-coordinate is on the vertical axis.

Values above $-3$ on the number line are greater than $-3$.

The red line shows where $y = 3$. Points above the line have a $y$-coordinate that is greater than $-3$.

The points where the $y$-coordinate is greater than $-3$ are point $A$, point $C$, and point $D$.

6.

To get to point $A$ from origin $(0, 0)$, we move left to $-2$ and up to $4$.

To get to point $B$ from origin $(0, 0)$, we move right $0$ and down to $-3$.

To get to point $C$ from origin $(0, 0)$, we move right to $4$ and down to $-4$.

7. To graph $(0, 8 \frac {1}{2}$, we move right 0 from the origin $(0, 0)$ then up $8 \frac{1}{2}$ from there.

To graph $( -4, -9)$, we move left 4 from the origin $(0, 0)$, then down 9 from there.

To graph $(-6, 5)$, we move left 6 from the origin $(0, 0)$, then up 5 from there.

$\left(0,8 \frac{1}{2}\right),(-4,-9)$, and $(-6,5)$ are graphed below.
