Find the equation of a line given the point and slope below. Arrange your answer in the form y = mx + b, where b is the constant

Nana76 [90]

Answer:

Step-by-step explanation:

an equation is : y = 10x+b

calculate b : this line passes by : (7;1) when x =7 y = 1

so : 10(7)+ b=1

b= -69

so : y = 10x-69

Here is a pattern of dots.

EleoNora [17]

The dots in the patterns are illustrations of a sequence or progression

The number of dots in step 10 is 84
The number of dots in step n is (n -1)^2+ 3

<h3>The number of dots in step 10</h3>

From the pattern, we have:

Step 0 = 3 dots
Step 1 = 4 dots
Step 2 = 7 dots
Step 3 = 12 dots

So, we have the following pattern

$T_n = (n -1)^2+ 3$

When n = 10, we have:

$T_{10} = (10 -1)^2+ 3$

T10 = 84

This means that, there will be 84 dots in step 10 and there will be (n -1)^2+ 3 dots in step n
