Day 24 Slopes, graphs and rate of change

Introduction In this session, we are interested in discussing the slopes, graphs of straight lines and rates of change all in one instance.

Vocabulary: Slope It refers to the steepness of a line Equation of a line It is a symbolic representation showing a collection of numbers that describe a straight line Variable rate of change This refers to an increase or decrease that is not constant with respect to a unit change. This can be done in the notebooks or on vocabulary cards. Whatever system you use 

From the graph, the y intercept is -1 From the graph, the y intercept is -1. To find the slope, we identify two points on the line shown by the arrow.
