Identifying Slope and Y-Intercept

Identifying Slope and Y-Intercept

...from graphs and equations!

Let's slow it down...

I recognize that there was a lot of information thrown at you during our lesson yesterday! Let's slow it down and take it step by step.

Today you will be reviewing two concepts:

1. Finding the slope and y-intercept from a graph

2. Finding the slope and y-intercept from an equation

By the end of this Quizizz, my hope is that we will feel more confident in these concepts!

1. Identify Slope and the Y-Intercept...

From a GRAPH!
