Find the equation of a line that contains the points (3,7) and (-6, 4). Write the equation in slope-intercept form, using

NikAS [45]

Answer:

$y=\frac{1}{3} x+6$

Step-by-step explanation:

$(3,7)(-6,4)$

Step 1. Find the slope (by using the slope-formula)

m = slope

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

$m=\frac{4-7}{-6-3}$

$m=\frac{-3}{-9}$

$m=\frac{3}{9}$

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

Step 2. Write the equation (using the slope and the points)

Here's how to do it:

Slope-intercept Formula $y=mx+b$ whrere m = slope and b = y-intercept

Plug in the slope into the Slope-intercept Formula

$y=\frac{1}{3} x+b$

Find the y-intercept (b) by using a point and substituting their x and y values

$y=\frac{1}{3} x+b$

Point: (3, 7)

$7=\frac{1}{3} (3)+b$

$7=1+b$

$b=7-1$

$b=6$

Step 3. Write the equation in Slope-intercept form

$y=mx+b$

$y=\frac{1}{3} x+6$

describe what would be true about the rate of change in a situation that could be represented by a graphed line and an equation

Andru [333]

If y=mx+b,

$\frac { dy }{ dx } =m$

You can't differentiate a constant, so dy/dx=m.

Using the sinusoidal function, it is found that the temperature will be below 0ºC between May and August.

<h3>What is a Sinusoidal function?</h3>

A sinusoidal function is a function that depends on a trigonometric function, having peaks according to the period and amplitude given by this function.

The function for the average monthly temperature, in m months after January, is given by:

$T(m) = 10\cos{\left(\frac{\pi}{6}\right)m} + 5$

Working with elementary angles, we have that:

$m = 10, T(0) = 10\cos{0} + 5 = 15$

$m = 3, T(3) = 10\cos{\left(\frac{\pi}{2}\right)} + 5 = 5$

$m = 6, T(3) = 10\cos{\pi} + 5 = -5$

$m = 9, T(3) = 10\cos{\left(\frac{3\pi}{2}\right)} + 5 = 5$

$m = 12, T(3) = 10\cos{2\pi} + 5 = 5$

From this, we have that it becomes negative after March, and positive before September, removing the middle two options.

Now, we have to test for April and May, that is, m = 4 and m = 5, hence:

$m = 4, T(4) = 10\cos{\left(\frac{2\pi}{3}\right)} + 5 = 0$

$m = 5, T(5) = 10\cos{\left(\frac{5\pi}{6}\right)} + 5 = -3.66$

Negative only in May, hence the temperature will be below 0ºC between May and August.
