2. Watch this video and try to answer the question

3. Each table represents a linear function. Write the equation representedx
f(x)
− 5 25
− 2 13 1 4
− 11 x
f(x)
− 9
− 7
− 4
− 3 6 5 11 9

4. Are the points on the same line?
If you are given 3 or more points and asked if they lie on the same line:
Check the slope from one point to the next
If all of the slopes are the same, they are on the same line. If not, the do not lie on the same line
**same slope, same line

5. Do the points lie on the same line
Do the points lie on the same line? If so, write the equation of the line.
A) B)
