Write an equation of a line that is perpendicular to the line 2x-3y+15=0

Step-by-step explanation:

The equation of the given straight line is 2x - 3y + 15 = 0.

Now, we can express the equation as 3y = 2x + 15

⇒ ..........(1)

The equation is in slope-intercept form and the slope is =

Therefore, the equation of a straight line which is perpendicular to (1) is  

{Where c is any constant}

{Since, the product of slopes of two perpendicular straight lines is -1}

Now, putting c = 1, we get the equation as . (Answer)

Buzz has 4 friends and Brock has 6.

The reason being is that Buzz has to have two less friend than Brock has, and yet still both have to add up to ten.
