Question

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

x /1, 2, 3 ,4
y /−2, −6, −10, −14


y =  x+

 

y=mx+b

THE X AND Y BELOW THE QUESTION IS A TABLE !!!!!!!!

Answer 1

Use first two points, (1,-2) and (2,-6) to find the slope, m.

 

m=(-6-(-2))/(2-1)=-4.

 

Substitute (1,-2) in y=mx+b to find the intercept.

 

-2=-4(1)+b

 

b=-2+4=2

 

y=-4x+2
