(-3, 6) & m = -¹/2 what’s this equation in point slope form

Gre4nikov [31]

The equation of the line in point-slope form is y - 6 = (-1/2)(x - (-3)) which can be simplified as x + 2y = 9.

The equation of a line that has a slope m, and passes through the point (x₁, y₁) is given by the point-slope form of a line, which can be shown as:

(y - y₁) = m(x - x₁).

In the question, we are asked to find the equation of the line in point-slope form, that passes through the point (-3, 6) and has a slope m = -1/2.

We know that the equation of a line that has a slope m, and passes through the point (x₁, y₁) is given by the point-slope form of a line, which can be shown as:

(y - y₁) = m(x - x₁).

Taking (x₁, y₁) as (-3, 6) and m = -1/2, in the point-slope form, we get the equation of the line as;

y - 6 = (-1/2)(x - (-3)).

This can be simplified as:

2y - 12 = - x - 3,

or, x + 2y = 9.

Thus, the equation of the line in point-slope form is y - 6 = (-1/2)(x - (-3)) which can be simplified as x + 2y = 9.

A retail shop accepts only cash or checks suppose that 45% of its customers carry cash 44% carry checks and 31% carry both cash

sergejj [24]

Answer:

Step-by-step explanation:

The number of customers carrying cash=45% = 0.45

The number of customers carrying checks= 44% =0.44

The number of customers carrying both = 31% = 0.31

So,

To find the probability we will write the expression:

cash+checks-cash or checks(both)=cash and checks

0.45+0.44-both=0.31

0.45+0.44-0.31=both

0.58=both....

Clara estimates that the length of a hiking trail is 5.75 km. She later learns that its actual length is 6.25 km. What is the pe

antoniya [11.8K]

8.0% is the answer. To solve these problems just do actual length minus her guess which gives you 0.5. Then divide what you got by the actual length. 0.5 divided by 6.25 is 0.08. Multiply that by 100. 0.08 x 100 is 8 which means the answer is 8.0% :)

A bank account balance, b, for an account starting with s dollars, earning an annual interest rate, r, and left untouched for n

Oduvanchick [21]

Well, assuming is "simple interest" rate

$\bf \qquad \textit{Simple Interest Earned Amount}\\\\
A=P(1+rt)\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{original amount deposited}\to& \$200\\
r=rate\to 4\%\to \frac{4}{100}\to &0.04\\
t=years\to &10
\end{cases}$
