200

What does the variable b stand for in the equation y= mx + b? 

Y-intercept. 

200

What is the y-intercept?

The point where the line crosses the y-axis. 

200

300

Define rate of change. Hint: change in ** / change in ** (**/**). 

1) Change in y / change in x. 

2) How much the dependent variable Y changes for every unit change in the independent variable X.

300

500

What is b? 

b = -2

500

What is one difference when writing/graphing parallel and perpendicular lines? 

Perpendicular: 

- Same y-intercept, opposite reciprocal slope

Parallel: 

- Different y-intercept, same slope
