Answer
See the explanation below.
Work Step by Step
The minimum values of x and y are $-20$ and $-4$. The maximum values of x and y are $2$ and $5$. The spacing for x and y are $1$ and $0.5$ m.
Let us consider the following coordinates:
$\left[ -20,2,1 \right]$ by $\left[ -4,5,0.5 \right]$
$\left[ -20,2,1 \right]$ represents that the minimum and maximum value of x-axis, that is $-20$ and $2$, respectively. The spacing of the consecutive tick marks is $1$.
$\left[ -4,5,0.5 \right]$ represents that the minimum and maximum value of y-axis that is $-4$ and $5$, respectively. The spacing of the consecutive tick marks is $0.5$.
