If the price of a shirt is reduced from $25 to $29 , what is the percent decrease in the price?

13.795%

Step-by-step explanation:

I think you mean that the shirt was reduced from 29 dollars to 25 dollars.

29 - 25 = 4 dollars

29 dollars x 13.795% =  4 dollars

y = 3x+4

step-by-step explanation:

to find the slope

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

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
