Answer:
y = -2x + 4
Step-by-step explanation:
Slope: (4-2)/5-1) = 2/4 = 1/2
Slope of the perpendicular line: -2
y-intercept: 2 - (-2)(1) = 4
Answer:
$99/$115 x 100% = 86.086% of the original price
So 100% - 86.086
= 13.9 = 14%
Or you could just do (115 - 99) x 100 which gets the same answer.
8x + y = 12 (substitute 3 for y)
<span>8x + 3 = 12 </span>
<span>8x = 9 </span>
<span>x = 9/8 </span>
<span>If y = 3 and 8x + y = 12, then x = 9/8.
HOPE THIS HELPS!!</span>
