It's already rounded to the nearest tenth, so it's still the same.
Answer:
I wish I could... T-T
Step-by-step explanation:
That perpendicular line will have slope , negative reciprocal to the slope of this line:
x +9y - 2 = 0 and its slop is - 1/9 { 9y = - x - 2 → y = (-1/9 )x - 2/9 }
So the slope of the perpendicular line will be ? 9
There fore the equation of the perpendicular line : y = 9x + b
“b” to be found by using other conditions
x intercept for this line ( put y = 0 ): -b/9
x intercept for 2x - 9y + 27 = 0 ( put y = 0) : - 27/2
Just equate the two: -b/9 = -27/2 → b = 243/2
y = 9x + 243/2
Answer : D
