What is the equation of (0,2) and (3,0)

ivolga24 [154]

Let's first find the slope. This is (y_2 - y_1)/(x_2 - x_1), where (x_1, y_1) and (x_2, y_2) are points.

For this problem, our slope is (0 - 2)/(3 - 0) = -2/3.

We can now use the point-slope formula to find the equation of our line:
(y - y_1) = m(x - x_1)
(y - 2) = -2/3(x - 0)
y - 2 = (-2/3)x
y = (-2/3)x + 2

The equation of our line is $\boxed{y = -\frac{2}{3}x + 2}$ .

Determine the two consecutive integers between which the given number is located on the number line.

navik [9.2K]

Answer:

between 3 and 4

Step-by-step explanation:

to find 19/6 located where on the number line

first we need to convert 19/6 to decimal

19/6 = 3.166...

so lets now see where 3.166 lies

it first lies between 3.160 and 3.170

but we need integer

so we go deeper and see

it lies between 3.100 and 3.200

and then we need to go more deeper to get an integer not decimal

now it lies between 3 and 4

Express the series using sigma notation. 2 - 6 + 18 – 54 + 162 ...

lidiya [134]

$2-6+18-54+162+\cdots=2(-3)^0+2(-3)^1+2(-3)^2+2(-3)^3+2(-3)^4+\cdots$
$=\displaystyle2\sum_{n=0}^\infty(-3)^n$
