The equation of the perpendicular line is: y = 5/3x - 6.

To find the perpendicular equation to y = -3/5x - 6, we need to take the reciprocal of the slope and multiply it by negative 1.

Here's how we get there:

Slope: The slope of the given equation is -3/5.

Reciprocal: The reciprocal of -3/5 is -5/3.

Negative reciprocal: Multiplying the reciprocal by -1 gives us 5/3.

Perpendicular equation: Therefore, the equation of the perpendicular line will be:

y = 5/3x + b

where b is the y-intercept.

We still need to find the y-intercept (b) to completely define the equation.

Here are two ways to find the y-intercept:

Method 1: Point-slope form

Choose a point on the original line. Let's use the y-intercept (0, -6).

Substitute this point into the equation of the perpendicular line:

-6 = 5/3 * 0 + b

-6 = 0 + b

-6 = b

Therefore, the y-intercept is -6.

Method 2: Slope-intercept form

Rewrite the original equation in slope-intercept form: y = -3/5x - 6

Since the perpendicular line intersects the original line, they share the same y-intercept (b) which is -6.

Therefore, the equation of the perpendicular line is: y = 5/3x - 6 .

Question

what would be the perpendicular equation to y=-3/5x-6 ?
