Question 90131: x=-3 - figure out gradient, y intercept and the line graph?

You can put this solution on YOUR website!
x=-3
The gradient or slope is UNDEFINED (does not exist) becasue the line is a straight vertical line.
The is no y-intercept because the line does not intercept or cross the y-axis.
To graph, plot these points:
(-3, 0) (-3, 1) (-3, 2) (-3, -1) and (-3 , -2) notice that all of the values for (x) are (-3) causing the graph to be a straight up and down, vertical line.
