What is the slope of the line through (-9,6) and (-6,-9)

1 answer:

7 0

$\text{The slope formula:}\ m=\dfrac{y_2-y_1}{x_2-x_1}\\\\\text{We have:}\\(-9;\ 6)\to x_1=-9;\ y_1=6\\(-6;\ -9)\to x_2=-6;\ y_2=-9\\\\\text{substitute:}\\\\m=\dfrac{-9-6}{-6-(-9)}=\dfrac{-15}{-6+9}=\dfrac{-15}{3}=-5$

Answer: m = -5

(2 fiths) to the -2nd power btw, how can i use the camra in this app

\cfrac{1}{a^n}\implies a^{-n}

\left( \cfrac{2}{5} \right)^{-2}\implies \left( \cfrac{5}{2} \right)^{+2}\implies \left( \cfrac{5^2}{2^2} \right)\implies \cfrac{25}{4}\implies 6\frac{1}{4}$

A bakery asks 75 customers to vote for a new bagel flavor. Onion flavor receives 33 votes. Cheddar flavor receives 42 votes. Use

m_a_m_a [10]

Using proportions, it is found that:

The fraction that shows the proportion of customers who voted for cheddar flavor is $\frac{42}{75}$

56% of customers voted for cheddar flavor.

A proportion is the number of desired outcomes divided by the number of total outcomes.

A percentage is the proportion multiplied by 100%.

In this question, 42 out of 75 customers voted for the cheddar flavor, hence:

$p = \frac{42}{75}$

That is, the fraction that shows the proportion of customers who voted for cheddar flavor is $\frac{42}{75}$

The percentage is:

$\frac{42}{75} \times 100\% = 56\%$

56% of customers voted for cheddar flavor.

Find the equation of a line that contains the points (6, -7) and (8,5). Write the equation in slope-intercept form.

Anna [14]

Answer:

y = 6x - 43

Step-by-step explanation:

(6, -7) and (8,5)

m=(y2-y1)/(x2-x1)

m=(5 + 7)/(8 - 6)

m= 12/2

m = 6

y - y1 = m(x - x1)

y + 7 = 6(x - 6)

y + 7 = 6x - 36

y = 6x - 43
