Graph the funxtion y=|x+2|-3
zhenek [66]
First you need to pick a number for y. Lets say you pick 0
Then you need to +3 to each side
Then you can say 3=x+2 or -3=x+2.
To find x you need to subtract 2.
You answer would  be (1,3) and (-5.-3)

What is the slope of a line with coordinates (5,3) and (1,2)?<br><br> A (1,4)<br> B 4<br> C (1,2)
Brilliant_brown [7]

Answer:

Slope (m) =

ΔY

ΔX

=

1

4

= 0.25

θ =  

arctan( ΔY ) + 180°

ΔX

= 194.03624346793°

ΔX = 1 – 5 = -4

ΔY = 2 – 3 = -1

Distance (d) = √ΔX2 + ΔY2 = √17 = 4.1231056256177

Equation of the line:

y = 0.25x + 1.75

or

y =  

1 x

4

+  7

4

When x=0, y = 1.75

When y=0, x = -7
