Question

What is the equation are perpendicular to the line -3x -6y=30 that passes through the point (-1,-4)​

Answer 1

You would have to switch the problem around and you know use negative

Answer 2

To find the slope of the perpendicular line, you can take the negative reciprocal of the slope of the line it is perpendicular to.

Taking the negative reciprocal of -1/5 gives 5.

Now we have y=5x+b, where b is the y-intercept. Since we know that the perpendicular line passes through the point (1,4), we can substitute those values into the equation we have to find b.
