In this problem, we need to determine the slope of the lines that are parallel and perpendicular to the line given in the graph shown.
00:08
So first of all, let us determine the slope of the line which has been given in the graph.
00:13
Let us consider that slope to be m.
00:16
Now, let us use the slope formula, which is y2 minus y1 divided by x2 minus x1, and this is the slope of a line which passes through the points x1 comma y1 and x2 comma y2.
00:30
Now, if we have a look at the graph, we can see that two points have been marked.
00:35
On the left -hand side, the point that has been marked is the point negative 8 comma negative 5.
00:41
And on the right -hand side, on the right side of the graph, we can see that the point that has been marked is the point 7, comma, 7.
00:50
So we have y2 minus 5.
00:52
We will have 7 minus negative 5 divided by x2 minus x1, so 7 minus negative 8...
