A. rotate a XYZ 90° counterclockwise about the origin and then translate it 8 units to the right
B. reflect A XYZ across the line y = -x and then translate it 4 units to the left
C. rotate A XYZ 90° clockwise about the origin and then reflect it across X'Y' that resulted from
the rotation
D. reflect A XYZ across the line y = -x and then reflect it across X'Y' that resulted from the first
reflection

step-by-step explanation:

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3

step-by-step explanation:

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form

if the angular bisector of an triangle bisects the opposite side, prove that the other two sides are equal.
