How do i solve |x|=2
2 answers:
Answer: x = 2 or x = -2
Step-by-step explanation: Absolute values means distance from zero.
If |x| = 2, that means that x's distance from zero on the number line is 2 units. So if you draw a number line like I have done on my whiteboard, you can see here are two different answers for this problem.
2 is 2 units from zero but also -2 is 2 units away from zero.
So our answer reads x = 2 or x = -2.
I have shown my work on my whiteboard below.

Answer:
y=-3x+5
Step-by-step explanation:
concepts: y=mx+b is slope intercept equation formula
m=slope
b= y intercept
Therefore we need to find the slope and y intercept
first find slope
m=
let y2 be 2
let y1 be -4
let x2 be 1
let x1 be 3
6/-2 = -3
m=-3
slope is -3
y= -3x+ b
we need find y intercept now
just plug in (1,2) into that equation
2=-3(1)+b
b=5
y=-3x+5
