OK the answer is x 5 but what does the answer mean. Given the coordinates. When youre dealing with linear equations you may be asked to find the slope of a line.
Did you notice that the x in the first point is really the y-coordinate of that point.
It means that if we substitute 5 for the missing coordinate in the first point the slope of the line between the two points will be equal to 2. Given the coordinates. OK the answer is x 5 but what does the answer mean. The position of points and elements can be found by Coordinate system.
