Writing Linear Equations from Graphs

Front

What is the equation of the line represented by the graph with a slope of -2 and a y-intercept of 4?

Back

y = -2x + 4

Front

In the equation y = mx + b, what does 'm' represent?

Back

y = -1/3x - 2

Front

How do you identify the slope from a graph?

Back

The slope is the rise over run, or the change in y divided by the change in x.
