Question

For each of the following, use the given information/picture to write an equation in point-slope form. Just the ones that have the yellow highlight.

Answer 1

4. y = -x + 8

9. y = 3/2x + 15

16. y = 1/2x -5

20. y = -3/5x + 16

13. y = -1/2x + 1

14. y = 3/4x - 2

Explanation:

4. 5=3(-1)+b = 8

9. 6=-6(3/2)+b=15

16.
`(1--2)/(12-6) =(3)/(6) = (1)/(2)`

-2= (1/2)6 + b = -5

20.
`(19-13)/(-5-5)= -(6)/(10) =-(3)/(5)`

19 = -3/5(-5) + b = 16
