Rodney's errors on each of the graphs given can be explained as in the explanation below.
<h3>Linear graphs of slope-intercept form equations</h3>
Rodney's error on each of the given linear graphs are as follows;
For y= 30x +10;
The slope of the graph is 30 and it's intercept is; 10. Hence, the graph should intersect/touch the y-axis at (0,10)
For y= (-1/2)x +5;
The slope of the given function is; -1/2 and hence, the graph should be a decreasing linear graph.
For y= x -2;
The slope and intercept of the given function are 1 and -2 respectively. On this note, the graphed line should intersect the y-axis at point (0, -2) and the graph should be an increasing linear graph.
