Question

What is the slope-intercept form of the function described by this table?

Enter your answer by filling in the boxes.

y =| | x + | |

Answer 1

y = - 3x + 4

Explanation:

m =
`(y_(2) -y_(1) )/(x_(2) -x_(1) )`

y -
`y_(1)` = m( x -
`x_(1)` ) Point-slope form

y = mx + b Point-intercept form

(1, 1)

(2, - 2)

m = (- 2 - 1 ) / (2 - 1) = - 3

y - 1 = - 3( x - 1 )

y = - 3x + 4
