What is the formula for the slope of a line segment whose endpoints are (x1,y1) and (x2,y2)?

Zolol [24]

Well, to find the slop regardless, you do (Y2 - Y1) Divided by (X2 - X1). It is the same thing when finding the slope of any line.

Ex: (4,5) and (8,6). What is the slope? (6 - 5) / (8 - 4) = 1/4 <--- Slope

Please leave a thanks because you are welcome. Hope this helps :)

2. From the top of a vertical cliff 40 m high, the object is 59.3m from the base of the cliff. Find the angle of depression to t

ArbitrLikvidat [17]

$34^{\circ}$ is the angle of depression from the vertical cliff.

Option: A

Step-by-step explanation:

Given that, Height of the cliff (opposite side) = 40m

Distance of object from the base of the cliff (adjecent side) = 59.3m

To find the angle of depression of the object. From trigonometric rule in a right angled triangle, we know that $\tan \theta=\frac{\text { opposite side }}{\text { adjecent side }}$ $\theta=\tan -1 \frac{\text { opposite side }}{\text { adjecent side }}$ Angle of depression = $\tan -1 \frac{\text { height of cliff }}{\text { Distance of object from the base of the cliff }}=\tan ^{-1} \frac{40}{59.3}=34^{\circ}$ Therefore, the angle of depression to the object is $34^{\circ}$ .

A line has a slope of -4 and passes through the point (0,5). Write the equation of this line in standard form. Be sure to expres

emmainna [20.7K]

Answer:

Final answer in standard form of the line is $4x+y=5$ .

Step-by-step explanation:

Given that slope of the lime m = -4

Now we need to find the equation of a line that has a slope of -4 and passes through the point (0,5). Write the equation of this line in standard form.

So plug the given slope m=-4 and the point (0,5) into point slope formula:

$y-y_1=m\left(x-x_1\right)$
