Describe how to find the equation of a line in slope-intercept form given a graph. Be specific!!! (Hint: 3 definitive steps)
What is...
1. find the slope using rise/run between two points on the line
2. find the y-intercept by location the point where the line crosses the y-axis and b equals the y-value of that point
3. plug the slope and y-intercept into the equation y = mx + b
Describe how to graph y = x - 2? Be specific!!! (Hint: 3 definitive steps)
What is..
1. Plot the y-intercept (0, -2)
2. Plot the rest of the points using the slope=rise/run so since m = 1, rise = up 1 and run = right 1 or rise = down 1 and run = left 1
3. Connect the points with a line
