To do this, you need to solve either one of the equations for y or x. I'm going to solve for y in the first equation:

6x + 3y = 9

Subtract 6x from both sides:

3y = 9 - 6x

Divide both sides by 3:

y = 3 - 2x

Now that you know what y is equal to, you can substitute it into the second equation:

2x + 3y = 1

2x + 3(3-2x) = 1

Distribute the 3:

2x + 9 - 6x = 1

Combine like terms:

9 - 4x = 1

Subtract 9 from both sides:

-4x = -8

Divide by -4:

x = 2

No substitute this 2 into either one of the equations to get y. I'm going to use the first:

6x + 3y = 9

6(2) + 3y = 9

12 + 3y = 9

Subtract the 12 from both sides:

3y = -3

Divide by 3:

y = -1

ANSWER:

x = 2

y = -1

You can always check by substituting the values into the equations.

The equation of the perpendicular line will be y = (4/3)x.

<h3>What is a linear equation?</h3>

A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

Then the equation of the perpendicular line will be given as

y = - (1 / m)x + c

The equation of line is y = -3/4 x + 1.

Then the equation of the perpendicular line will be

y = 4/3 x + c

The equation is passing through (9, 12), then we have

12 = 4/3 (9) + c

12 = 12 + c

c = 0

Then the equation of the perpendicular line will be y = (4/3)x.

More about the linear equation link is given below.
