Question

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

Answer 1

Answer:

y = - 3x + 4

Step-by-step explanation:

m = $\frac{y_{2} -y_{1} }{x_{2} -x_{1} }$

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
