: Find the slope between the two points given. Then, use the slope and point ONE to write the equation of the line in Point-Slop

Ierofanga [76]

Answer:

slope: $\bold{m=3}$

equation: $\bold{y-2=3(x-1)}$

Step-by-step explanation:

$m=\dfrac{y_2-y_1}{x_2-x_1}\\\\(1,\,2)\ \implies\ x_1=1\,,\ y_1=2\\(0,\,-1)\ \implies\ x_2=0\,,\ y_2=-1\\\\m=\dfrac{-1-2}{0-1}=\dfrac{-3}{-1}=3$

$y-y_1=m(x-x_1)$ - point-slope form of Equation of the Line

$x_1=1\,,\ y_1=2\,,\ m=3\\\\equation:\\{}\qquad\qquad y-2=3(x-1)$

HELP ASAP PLEASE!

tatyana61 [14]

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

Plug in the points. (2,3) (9,7)

m= (7-3)/(9-2)

m= 4/7

Slope= 4/7

I hope this helps!

There are 6 minutes of commercials for every 24 minutes of television. How many minutes of commercials are there in 1 hour and 3

mafiozo [28]

Answer:

$16\ minutes$

Step-by-step explanation:

For every $24\ minutes$ of television time of commercials = $6\ minutes$

% of commercials $\=frac{6}{24}\times 100=25\%$

Now when time of television $=1\ hour\ 36\ minutes=60+36=96\ minutes$

$25 \%\ of 96=\frac{25}{100}\times 96=\frac{96}{4}=16\ minutes$
