Use the coordinates of the labeled point to find the point slope equation of the line

Mathematics
1 answer:
Karo-lina-s [1.5K]3 years ago
4 0

Answer:

D. y + 1 = -2(x - 2)

Step-by-step explanation:

Point-slope form equation is given as y - b = m(x - a), where,

(a, b) = a point of the graph.

m = slope of the graph

Find the slope of the graph:

Slope = \frac{rise}{run} = \frac{-4}{2} = -2

Using the point (2, -1) and the slope, m, = -2, we can derive the equation in point-slope form by substituting a = 2, b = -1, and m = -2 into y - b = m(x - a).

✅The equation would be:

y - (-1) = -2(x - 2)

y + 1 = -2(x - 2)

Elza [17]
Absolute or modulus always gives a positive number.
For example, when I take absolute value of 4, I get
|4| = 4 and when I take absolute value of -4, I get |-4| = -(-4) = 4.

Therefore, no matter what the sign of quantity is, absolute or modulus will always make it positive. 
Therefore,

Suppose you live 4.4 miles from a hill. From your home you see a plane directly above the hill. Your angle of elevation to the p
IrinaVladis [17]
█ Explanation <span>█

Let's call the missing altitude 'x'. 

</span><span>✦ To find the plane's altitude, find the tan of 30 degrees. The side opposite is going to be x, while the side adjacent is going to be 4.4 miles. 
</span>✦ Tan(30)= \frac{x}{4.4}
✦ 5.7735= \frac{x}{4.4}
✦ x=4.4*.57735
✦ x=4.4*.55735
✦ x=2.54 mi
<span>✦ We usually write altitude in feet.

Which of the coordinate points below will fall on a line where the constant of proportionality is 1/4? Select all that apply. A)
kompoz [17]

Answer:

A) (4,1)  C) (12,3) D) (20,5)

Step-by-step explanation:

Required

Which has a constant of proportionality of 1/4

To solve this, we make use of:

y = kx

Where k is the constant of proportionality.

Solve for x

k = y/x

<u>Testing the given options</u>

A) (4,1)

k = y/x

k =1/4

B) (8,12)

k = y/x

k =12/8

k =3/2

C) (12,3)

k = y/x

k = 3/12

k = 1/4

D) (20,5)

k = y/x

k = 5/20

k = 1/4

E) (12,6)

k = y/x

k =6/12

k =1/2
