Write the equation in y=mx+b form please????

ANSWER

$y = - 2x - 5$

EXPLANATION

We can use any two points to determine the slope.

The line passes through;

(-3,1) and (-5,5).

The slope is given by

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

This implies that;

$m = \frac{5 - 1}{ - 5 - - 3}$

$m = \frac{4}{ - 2} = - 2$

We can now find the equation using the formula;

$y-y_1=m(x-x_1)$

$y - 1 = - 2(x + 3)$

Expand:

$y = - 2x -6 + 1$

$y = - 2x - 5$

The frequency of the musical not B3 is about 246.94 Hz. What is the frequency of the note a perfect fifth below B3

Crazy boy [7]

Notes separated by a perfect fifth have a frequency ratio of 3:2.
The frequency of the note a perfect fifth below B3 will be
246.94×2/3 = 164.62667

The appropriate choice is ...
164.63 Hz

Suppose that the probability that your mail is delivered before 2 pm is .90. What is the probability that your mail will be deli

iren2701 [21]

Given that the probability of mail being delivered is 0.90, to evaluate the probability that the mail will be delivered before 2 p.m for 2 consecutive days will be evaluated as follows:
Let the probability that the milk will be delivered before 2 p.m be P(x). Since the two days are independent events, the probability of the mail being delivered before 2 p.m in 2 consecutive days will be:
P(x)×P(x)
=0.9×0.9
=0.81

Through: (3,3), slope=7/3

Yuri [45]

Answer:

y = $\frac{7}{3}$ x -4

Step-by-step explanation:

The slope-intercept form of an equation of a line is given by:

y = mx + b, where m = slope and b = y-intercept

Given the slope and point on a line, you can solve for 'b' in the equation:

(3, 3) - x = 3, y = 3

slope = $\frac{7}{3}$

Plug into the equation:

3 = $\frac{7}{3}$ *3 + b

3 = 7 + b

-4 = b

y = $\frac{7}{3}$ x - 4
