Why does the m in the general slope equation mean slope?

Answer 1

The general equation is y = mx + c

This means that the y value is found by muliplying x by a constant and then adding a different constant.

In other words the slope is the change in y with relation to the change in x

In other words, for every 1 x value, you go accross, you go up m. So if m = 10, you go up 10, for every one 1 unit you move along to the right. If m = -10 you go down by 10 every time you move one unit to the right

Hope that helps
