Perpendicular to the line x - 5y = 9; containing the point (2, 4)

Mathematics
1 answer:
dezoksy [38]2 years ago
6 0

Answer:

y=-5x+14

Step-by-step explanation:

x-5y=9

x-9=5y

y=\frac{1}{5}x-\frac{9}{5}

The slope for this line is: 1/5

The product of the slopes of any two perpendicular lines equals -1.

So the slope for the perpendicular line will be -5.

The point-slope formula=

Given slope m and a point on the line: (X, Y), the equation of the line will be:

y-Y=m(x-X)

So the equation for the perpendicular should be:

y-4=(-5)(x-2)

Simplify:

y-4=-5x+10

y=-5x+14

Laura bought a square canvas to paint a picture of her cat one side measured 22 centimeters what is tha area of the canvas
Olin [163]
Hi there!

To start, squares are a shape in which all of its sides are congruent to one another. Knowing the length of one side would mean that you would know the length of all the other sides. 

Because you know that one side measures 22 cm, you can conclude that all the other sides of the square are also at a length/width of 22 cm.

Next, you will find the area of the square. 

Because the area formula is Area=Length * Width, you can easily find the area of the square by multiplying 22*22 since the length and width of any square is the same.

When you simplify 22*22, you should get 484.

Therefore, the area of the square canvas would be 484 cm squared.

Hope this helps and have a marvelous day! :)
