Abe has 150 t-shirts to sell before the playoffs begin. The table shows the linear relationship between the number of t-shirts remaining, y, and the number of days he has been selling, X. T-shirt Sales Number of Number of Days T-shirts Remaining х Which function can be used to find y, the number of t-shirts remaining after x days?

Y= -12x + 150

Step-by-step explanation:

1. You do the change in y over the change in x to get the slope.

y1 - y2 / x1 - x2 and you get the slope of -12

2. Making a point-slope form equation

y-y1=m(x-x1)

y-138= -12(x-1)

3. Turning point-slope form equation to slope-intercept

y-138= -12(x-1)

distributive property

y-138=-12x+12

add 138 on both sides

y=-x+1
