Write an equation of a line in point-slope, slope-intercept, and standard form that has
Inga [223]

Answer:

(a) y + 4x - 14 = 0

(b) y = -4x + 14

(c) y + 4x = 14

Step-by-step explanation:

The formula for calculating the equation of line in point - slope form is given as :

y-y_{1}  = m(x-x_{1} )

where m is the slope

Given from the question :

m = - 4

x_{1} = 2

y_{1} = 6

Substituting into the formula , we have :

y - 6 = - 4(x - 2)

y - 6 = -4x + 8

y + 4x - 6 - 8 = 0

y + 4x - 14 = 0

Therefore :

(a) the equation of the line in point - slope form is y + 4x - 14 = 0

(b) to write it in slope - intercept form , we will make y the subject of the formula , which will give : y = -4x + 14

(c) the equation of line in standard form is ; y + 4x = 14

Triangle CAT is equilateral and centered at the origin. How many degrees will it need to be rotated counterclockwise about the o
tankabanditka [31]

Answer:

-120 degrees.

Step-by-step explanation:

This triangle has a rotational symmetry of 3  (it repeats its  orientation 3 times as it makes a complete circle around the center),  so the angle of rotation is 360 / 3 = 120 degrees.

As the rotation is counter clockwise  strictly speaking the answer is -120 degrees.
