Step 1: Y= 27 - 4x
To find X - intercept / zero, substitute Y = 0
0 = 27 - 4x
Step 2: 0 = 27 - 4x
Move variable to the left-hand side and change it's sign.
4x = 27
Step 3: 4x = 27
divide both sides of the equation by 4
X = 27/4
solution: X = 27/4
Alternate form: X = 6 3/4, X = 6.75
80 miles because if 1=20 then 2=40 3=60 4=80
It
can be described useing two other undefined terms :- point & line
First u add all of them and then multiple 2 numbers then theres ur answer
X=6 because 2*6=12 and 12+4=16
