Question

Write the equation of the line that goes through (-3.9, -1.4) and is PERPENDICULAR to 6x + 2y = 9

Answer 1

9514 1404 393

Answer:

  10x -30y = 3

Step-by-step explanation:

In general form, you can start by swapping the x- and y-coefficients, negating one of them. To find the new constant for the equation, substitute the values for the given point

  2x -6y = 2(-3.9) -6(-1.4)

  2x -6y = 0.6

Multiplying by 5 will make the numbers be integers, so will put the equation in standard form.

  10x -30y = 3
