I think it is decreasing by -4

Answer:

y = -4x+2

Step-by-step explanation:

We have 2 points (1,-2) and (4,-14)

We can find the slope using

m = (y2-y1)/(x2-x1)

  = (-14--2)/(4-1)

  = (-14+2) / (4-1)

  = -12/3

  = -4

We can use point slope form to write an equation

y-y1 = m(x-x1)

y--2 = -4(x-1)

Distribute the -4

y+2 = -4x+4

Subtract 2 from each side

y+2-2 =-4x +4-2

y = -4x+2

This is in slope intercept form  ( y= mx+b)  where the slope is -4 and the y intercept is 2
