Answer:

I'm not sure to help you but I can help you out a bit.

Since x - 2y = 1,

x = 1+ 2y

This is expressing x in terms of y.

In addition,

2y = x - 1

y = (x-1)/2

This is expressing y in terms of x.

Write the equation of a line perpendicular to y= -1/3x + 5 and passes through the point (6, 4).

Levart [38]

Answer:

y = 3x - 14

Step-by-step explanation:

Perpendicular lines will have a opposite reciprocal slope, so the slope will be 3.

Plug in the slope and given point into y = mx + b, then solve for b:

y = mx + b

4 = 3(6) + b

4 = 18 + b

-14 = b

Plug in the slope and y intercept into y = mx + b

y = 3x - 14

So, the equation of the line is y = 3x - 14
