Question

8. Jefferson received a Star Wars X-Wing Lego set for Christmas. The equation y - 555 = -22(x - 12) represents y as a function of x, where y is the number of Lego piec Jefferson has left to build and x is the number of minutes he has been building. Use this information to mark a-c as true or false. If false, rewrite the statement correctly. 1.Jefferson removes 22 lego pieces a minute from the box.

Answer 1

we have the equation

y-555=-22(x-12)

this is the equation of the line in point slope form

where

m=-22

point (12,555)

Verify each statement

a) is true

b) is false

the number of pieces of lego is the y-intercept

so

the value of y when the value of x is equal to zero

For x=0

substitute in the equation above

y-555=-22(0-12)

y-555=264

y=264+555

y=819 pieces

therefore

the number of pieces is 819

c) is true
