Write an equation in point slope and slope intercept form of a line that passes through the given point and has the given slope

Evgesh-ka [11]

Answer:

Point-Slope: $y+4=-\frac{1}{2}(x+3)$

Slope-Intercept: $y=-\frac{1}{2}x-\frac{11}{2}$

Step-by-step explanation:

The point-slope formula is $y-y_{1}=m(x-x_{1} )$ . The slope-intercept formula is $y=mx+b$ . Since we are given the point and slope, we can directly plug it into the point-slope formula.

Point-Slope

$y-(-4)=-\frac{1}{2}(x- (-3))$

$y+4=-\frac{1}{2} (x+3)$

To find the slope-intercept form, we can manipulate the point-slope form to get the slope-intercept form.

Slope-Intercept

$y+4=-\frac{1}{2}x-\frac{3}{2}$

$y=-\frac{1}{2}x-\frac{11}{2}$

Solve the equation on the interval [0, 2π). <br><br> cos x + 2 cos x sin x = 0

vekshin1

Take a common factor of cos(x)
$\cos(x) (1 + 2 \sin(x) ) = 0$
then by zero multplication rules
$\cos(x) = 0$
$x = \frac{\pi}{2} \: x = \frac{3\pi}{2}$
and when
$1 + 2 \sin(x) = 0$
so
$2 \sin(x ) = - 1$
$\sin(x) = \frac{ - 1}{2}$
so
$x = \frac{3\pi}{2} - \frac{\pi}{3}$
and
$x = \frac{3\pi}{2} + \frac{\pi}{3}$
