Write the equation of the line that passes through points (-4, 5) and (0,13) in slope-intercept form.

LiRa [457]

Answer:

The answer is

$y = 2x + 13$

Step-by-step explanation:

Remember:

$Slope-intercept form: \: \\ y = mx + b \\ \\ m = slope \\ b = y - intercept$

$M = \frac{y_2 - y_1}{x_2 - x_1}$

First: Find the slope.

$M = \frac{13 - 5}{0 - ( - 4)} = \frac{8}{4} = 2$

Second: Solve for the y-intercept

$y = mx + b \\ 5 = 2( - 4) + b \\ 5 = - 8 + b \\ \frac{+ 8 = + 8 \: \: \: \: \: \: \: \: }{13 = b}$

Third: Plug in.

$y = mx + b \\ y = 2x + 13$

Most intruments produce notes across ranges called octaves which are made up of 8 notes how many octaves do 51 notes span?

mojhsa [17]

Answer: 51 notes span 6 octaves.

Step-by-step explanation:

The word "octave" is a Latin word that means "eight".

In an instrument, Each octave is made up of 8 musical notes.

If we have 51 notes , the number of octaves can be made in it = $\dfrac{51}{8}$

$=6.375\approx6\ \ \ \ \ \text{[Rounded to the nearest whole number]}$

Hence, 51 notes span 6 octaves.
