To make a table, substitute different values of hh into $a=50h+50$.

Since hh represents time, which can't be negative, only substitute values of hh such that

$h\ge 0h\ge 0:h|50h+50|\left(h,a\right)0|50\left(0\right)+50$

$=50|\left(0,50\right)1|50\left(1\right)+50$

$=100|\left(1,100\right)2|50\left(2\right)+50$

$=150|\left(2,150\right)3|50\left(3\right)+50$

$=200|\left(3,200\right)4|50\left(4\right)+50$

$=250|\left(4,250\right)5|50\left(5\right)+50$

$=300|\left(5,300\right)$

Plot the points from your table and then draw a line passing through the points to sketch the graph of the equation. Then label the vertical axis as Total Charge (\$) and the horizontal axis as Number of Hours:
