Let's try a line

y = mx + b

From (0,4):

4 = 0x + b

b = 4

So far we have

y = mx + 4

From (1,1)

1 = m(1) + 4

-3 = m

Our rule is y = -3 x + 4

Let's check the other points:

-3(-4)+4 = 12+4 = 16 good

-3(4)+4 = -12+4 = -8 good

-3(9) + 4 = -23 good

Answer: y = -3 x + 4

Find the Perimeter of this shape:

LiRa [457]

Answer:

76 cm

Step-by-step explanation:

To find perimeter, you find the total of the sides.

A rectangle has 4 sides, and 2 equal sides.

So, add 14+14 which is 28.

Then add 24+24 which is 48.

Now add 48 and 28.

48+28=76

Final answer

76 cm

The standard form of the equation of a circle is (x−3)2+(y−1)2=16.

____ [38]

$Use:(a-b)^2=a^2-2ab+b^2\\\\(x-3)^2+(y-1)^2=16\\\\x^2-2\cdot x\cdot3+3^2+y^2-2\cdot y\cdot1+1^2=16\\\\x^2-6x+9+y^2-2y+1=16\\\\x^2+y^2-6x-2y+10=16\ \ \ |-16\\\\\boxed{x^2+y^2-6x-2y-6=0}$
