It wants you to come up with three events. You'll place them on the line right above, where you think they would go.

For example, if your first event was "seeing a unicorn" you would plot it by "impossible." Some things have a fifty fifty chance, or are likely, like you finding a penny. Use any scenario you can think of. How likely is it that it would come true?

Write the equation of a line in slope intercept form of a line that has a slope of 1/2 and contains (-4,1)
Delicious77 [7]
The general form of the line is:
y = mx + c where:
m is the slope 
c is the y-intercept

Now, we are given that the slope = 1/2.
The equation now became:
y = (1/2) x + c

Now, we need to get the y-intercept. We are given that (-4 ,1) belongs to the line. Therefore, this point satisfies the equation of the line. Based on this, we will substitute with this point in the equation above and solve for c as follows:
y = (1/2) x + c
1 = (1/2)(-4) + c
1 = -2 + c
c = 1+2
c = 3

Based on the above, the equation of the line is:
y = (1/2) x + 3

What is the slope of the line through (-1,4) and (5,2)
butalik [34]

Answer:

Slope (m) = -\frac{1}{3}

Step-by-step explanation:

Use the following equation:

Slope (m) = \frac{y_2 - y_1}{x_2 - x_1}

Let:

(x_1 , y_1) = (-1 , 4)\\(x_2 , y_2) = (5 , 2)

Plug in the corresponding numbers to the corresponding variables:

m = \frac{2 - 4}{5 - (-1)} = \frac{2 - 4}{5 + 1} = \frac{-2}{6}

Simplify. Divide common factors from both the numerator and denominator:

\frac{(-\frac{2}{6})}{\frac{2}{2} } = -\frac{1}{3}

-\frac{1}{3} is your answer.

Using the following triangle, what is the cosine of angle B?
Nikolay [14]

Answer:

  cos(B) = a/c

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you that ...

  Cos = Adjacent/Hypotenuse

The leg adjacent to angle B is "a". The hypotenuse is "c", so the desired cosine is ...

  cos(B) = adjacent/hypotenuse = a/c
