Day 5

• Objective: Students will be able to write an equation of a line given data points.
•  To find the slope of the line, use your two points and do y2-y1 over x2-x.  To find the y-intercept (or b) you choose one of the two points and plug the y value and the x value into your new equation with the slope you found. (y=mx+b)

Quiz!!
