For today's homework, you will need to recreate work the teacher did last night on their computer. The teacher drew a triangle with vertex A at(1,4) and vertex B (3,2). The teacher then transformed it to
produce the triangle shown below. You need to find the teacher's original triangle and the
transformations they used to create this image. Choose the correct way to find the transformations. Select
all that apply. (Hint: It is a rigid transformation.)

what i would say the best answer is a. 40.5

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
