$y=-\frac{1}{2}x-8$

Step-by-step explanation:

(-4,-6)(-2,-7)

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

m = slope

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

$m=\frac{-7--6}{-2--4}$

$m=\frac{-1}{2}$

$m=-\frac{1}{2}$

Step 2. Create the equation of a line that has a slope of $-\frac{1}{2}$

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

Step 3. Find the y-intercept

To do this, use any of the two points and substitute their x and y values

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

point: (-2,-7)

$(-7)=-\frac{1}{2}(-2)+b$

(-7)=1+b

b=-7-1

b=-8

Step 4. Write the equation in Slope-intercept form

y=mx+b

$y=-\frac{1}{2} x-8$

x = 4394.9

Step-by-step explanation:

x.sin(21) = __1575__ . x

cross out the x from both side then

_x.sin (21) = _1575

sin(21) sin(21)

x = 4394.9

tell me if that is the right answer

Mark me as brainliest if i got it right
