What is the equation of the line perpendicular to the line y=4/9x-2 that passes through the point (4,3)?

dalvyx [7]

Y - y₁ = m(x - x₁)
y - 3 = -2¹/₄(x - 4)
y - 3 = -2¹/₄(x) + 2¹/₄(4)
y - 3 = -2¹/₄x - 9
+ 3 + 3
y = -2¹/₄x - 6

3[–x + (2 x + 1)] = x – 1

photoshop1234 [79]

Answer:

Step-by-step explanation:

$3[-x + (2 x + 1)] = x -1\\\\\mathrm{Expand\:}3\left(-x+\left(2x+1\right)\right):\quad 3x+3\\3x+3=x-1\\$

Collect like terms

$3x -x =-1-3$

Add similar elements

$2x = -4\\\\\mathrm{Divide\:both\:sides\:by\:}2\\\frac{2x}{2}=\frac{-4}{2}\\\\Simplify\\\\x = -2$
