Given:

Line of the graph

To find:

Equation of the line

Solution:

Take any two points on the graph of the line.

Let the points are (0, 3) and (3, 0).

Slope of the line:

$m=\frac{y_2-y_1}{x_2-x_1}

Here, x_1=0, y_1=3, x_2=3, y_2=0

$m=\frac{0-3}{3-0}

$m=\frac{-3}{3}

m = -1

b = y-intercept

y-intercept of the graph is the point which x = 0.

y-intercept is 3 when x = 0.

⇒ b = 3

Equation of a line:

y = mx + b

y = -1(x) + 3

y = -x + 3

The equation of the line is y = -x + 3.

Sam is tiling a floor. He will use the same repeating pattern for the entire floor. The rule is "Blue Tile, White Tile, Black Ti
snow_lady [41]

If he uses 85 tiles, 28 tiles will be black

<h3>Sequence and Pattern</h3>

The formation of the tiles of the floor follows an arithmetic sequence or pattern

The pattern is given as:

  • Blue
  • White
  • Black

<h3>Formation of the tiles</h3>

Given that the total number of tile used is 85, and the black tile is always in the third position.

The highest number less than or equal to 85 that is divisible by 3 is 84.

Next, we divide 84 by 4

n = \frac{84}{3}

n = 28

Hence, 28 of the tiles will be black
