Slope intercept form: y=
−5
7
x+5
The graphing points would be (0,5)(7,0)
144 is the lowest hoped this helped
First we have to find the vertex (h,k) h is also x and it also is the a xis symmetry
1st: group the number
(X2+6x)-9
2nd: use b/2
6/2 = 3 , 3^2= 9
(X2+6x+9)-9-9
(X2 + 3)-18
Vertex is 3,-18 so the symmetry is 3
You would get back $1
$9.99-$1.50= $8.49 <--- 15% off
$8.49x.06= .51 cents <--- Taxes
$8.49+.51<--cents= $9 <--- Total cost of the T-shirt
