what is the equation in point-slope form of the line passing through (0, 5) and (−2, 11)? (1 point) y − 5
makkiz [27]

According to the question, the line is through the points (0,5) and (-2,11)

To calculate the slope using standard formula that is :

m = \frac{(y(2)-y(1))}{(x(2)-x(1))} = \frac{(11-5)}{(-2-0)} =\frac{6}{-2} = -3

Now the slope equation will be: m(x(2)-x(1)) = (y(2)-y(1))

y-5 =(-3)(x-0) = y = -3(x)+5

The slope-intercept form is:y = -3x+5

What is the equation of the line?

To represent the set of points in an algebraic form is known as the equation of line. The set of points represent lines in the coordinate system. The parameters can be calculated and those parameters are slope and y-intercept.

To learn more about the equation of the line from the given link:

By right triangle trigonometry, the sine of the measure of an angle is the ratio of the opposite side of this angle to the hypotenuse.

Thus, \displaystyle{\sin27^{\circ}= \frac{34}{x}


\sin27^{\circ} is a constant which can be found using a calculator:

with calc in pc: view → scientific → 27→sin = 0.45399, 

thus x=34/0.45399=74.89


Answer: 74.89

Ede4ka [16]

Answer:

ROCK 2.3 kg

is about 22.5N

Step-by-step explanation:

To convert kg>>>>N

You multiply by 9.8 (this is good for estimating, but use more decimal places like, 9.80665 for more exact calculations).

You can divide N÷9.8 to find kg
