The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis.

Answer:

In the equation of a straight line (when the equation is written as "y = mx + b"), the slope is the number "m" that is multiplied on the x, and "b" is the y-intercept (that is, the point where the line crosses the vertical y-axis).

Step-by-step explanation:

Step 1: To find out, suppose (x1, y1) and (x2, y2) are two

points on the graph of y = mx + b.

Step 2: Then y1 = mx1 + b and y2 = mx2 + b.

Step 3: Use algebra to simplify

y2 – y1

x2 – x1

Step 4: Or try Rise/Run.

First, find the number of people who need chairs.

18 + 9 + 15 + 12 = 54

Subtract the people who cant come

54 - 6 = 48

Divide by amount of chairs per row

48/6 = 8

C. 8 rows of chairs are needed.

Simple....

so we have to determine if the value is less than the base....

$2^{3} =8$ .... is 8<2? No.

$\frac{5}{6} ^{3} = \frac{125}{216}$ No....

$3^{1}=3$ Is 3<3? No....

$\frac{5}{2} ^{3} = \frac{125}{8}$ No.....

$1^{3} =1$ No.....

Answer:

The 6 Lego kits can be selected from the 9 available Lego kits in 84 ways.

Step-by-step explanation:

Use combinations to solve this problem.

Combination is defined as the selection of <em>r</em> elements from <em>n</em> distinct objects irrespective of the order. The objects cannot be replaced.

There are 9 Lego kits available.

And the total number of children is 6.

That is, we need to select 6 Lego kits from the 9 available Lego kits.

6 Lego kits can be selected from the 9 available Lego kits in $9\choose 6$ ways.

Solving the combination as follows:

${9\choose 6}=\frac{9!}{6!\times(9-6)!} \\=\frac{362880}{720\times6}\\ =84$

Thus, there are 84 ways to select 6 Lego kits from 9 available Lego kits.
