Line perpendicular to a given line is = 1/m
To find m, use m =y2-y1/x2-x1 formula
m = (8-(-3))/(-7-4)
m = 11/-11,
m = -1
Use y= mx+c to find equation of line
Plug in a pair of values,
-3= -1(4)+ c
c= 1
Thus, equation is:
y = -x+1
Equation of line perpendicular to this line is:
y= x+1

Given:
______________________________________________
$18.99 per 340.23 grams ;
and given:
1 gram ≈ 0.03527 oz (ounces) ;
______________________________________________
Find the unit price per OUNCE (oz).
______________________________________________
Given: $18.99 per 340.23 grams ;
Convert: "340.23 grams" to "ounces (oz)".
Given: "1 gram ≈ 0.03527 oz" ;
340.23 grams = (340.23 * 0.03527) oz. = 11.9999121 (about "12 oz.").
So, $19 / 12 oz. = ? dollars per UNIT OZ. ; =
(19/12) dollars per oz. = (19÷12) dollars per oz. = $ 1.58333 ; which corresponds to: Answer choice: [C]: $1.58 .
