The equation of the line is C. 1X/2 -2
How you figure this out is you first say when x is zero y is what?
y= 1/2 (0) - 2
You would then see that y=-2 (0,-2)
Plot that point
Next you need to find the slope of the line.
Remember slope is rise over run.
When you 'rise' up one (from -2) and 'run' 2
you are now at the point (2,-1) which is on the line.
You can continue doing rise/run along the line to check your answer.
I hope this makes sense! Let me know if you have any questions :)

Find the non-extraneous solutions of the square root of the quantity x plus 9 minus 5 equals quantity x plus 4

Sedaia [141]

I"m guessing you mean
$\sqrt{x+9} -5=x+4$
add 5 to both sides
$\sqrt{x+9}=x+9$
square both sides
x+9=x²+18x+81
minus x+9 both sides
0=x²+17x+72
factor
what 2 numbres multiply to get 72 and add to get 17?
8 and 9
0=(x+8)(x+9)
set to zer

0=x+8
x=-8

x+9=0
x=-9

test each

$\sqrt{-8+9} -5=-8+4$
$\sqrt{1} -5=-4$
1-5=-4
-4=-4
true

$\sqrt{-9+9} -5=-9+4$
$\sqrt{0} -5=-5$
-5=-5
true

the solutions are x=-9 and -8
