Finding Equations of Lines with Two Points

Write equation of the line containing (2,6) and (3,1)

• y = 5x - 14

• y = -5x - 14

• y = -5x + 16

• y = -5x + 6

• A

• B

• C

• D

Remember RATE OF CHANGE means SLOPE. Find the slope by using RISE/RUN or using List & Spreadsheet, Data & Statistics, Menu 4,6,1.

• A

• B

• C

• D

Graph the given equation on a GRAPH PAGE and check which answer choice matches. Make sure to use MENU, TRACE, GRAPH TRACE and match the x-intercept.

• F

• G

• H

• J

Remember equations are written as y=mx+b. Create the equation by finding the slope from rise/run and the y-intercept by looking at where it crosses the y-axis.

You can also create an equation by making a List & Spreadsheet, Data & Statistics, Menu 4, 6, 1.

• F

• G

• H

• J

• Find the slope of AB

• Find the distance of BC

• Find the midpoint of AB

• Use negative reciprocal of the slope of AB

When we are finding equations for medians, altitudes, and perpendicular bisectors, we are really just finding equations of _______________________
