y = -0.25x - 6

please explain how you got your answer. thank you!

Answer 1

y=1.5x+1; x= -0.6

y= -0.25x-6; x= -24

Explanation:

y=1.5x+1

0=1.5x+1 (To find x-intercept/xero, substitute y=0)

-1.5x=1

x= -2/3 or x= -0.6

y= -0.25x-6

0= -0.25x-6

0.25x= -6 (Move variables to the left-hand side and change its sign)

x= -24
