One of the most convenient ways of finding or calculating for the
midpoint of the line segment is to get the average of the coordinates of the
points.
Average of abscissa = (0 + 0) / 2 = 0
Average of ordinate = (0 + 15) / 2 = 7.5
Hence, the midpoint of the line segment is equal to (0, 15/2).
The value of the y-intercept is 15/2.

<span>An element is a pure substance that cannot be broken down by further chemical techniques. Therefore you could try heating, cooling, electrolysis or other methods to see if it was an element or a compound.</span>
- Endothermic reaction : so the energy of product is higher than the energy of reactant.
- Catalyst lowers the activation energy so it increase the rate of reaction.
