First we need to find the slope of the original equation
2x - 3y = 3
-3y = -2x + 3
y = 2/3x - 1....the slope here is 2/3.
However, we need a perpendicular line...so we need to use the negative reciprocal slope. All that means is flip the slope and change the sign.
slope 2/3.....flip.....3/2....change the sign...-3/2.
so our perpendicular line will need a slope of -3/2.
y = mx + b
slope(m) = -3/2
(-8,2)...x = -8 and y = 2
now we sub and solve for b, the y int
2 = -3/2(-8) + b
2 = 12 + b
2 - 12 = b
-10 = b
so our perpendicular line is : y = -3/2x - 10
The cheaper option is Best Buy where the TV would close $455 compared to Micro Center which out be $480.
X - 2 = -5
x = -5 + 2
x = -3
(x-2)^2 + 5x - 10...when x = -3
(-3-2)^2 + 5(-3) - 10
-5^2 - 15 - 10
25 - 15 - 10
10 - 10
