Answer:
y=3x+7
Step-by-step explanation:
y=mx+c
m=3 parallel lines have the same gradient
(-2,1)
(x,y)
y=mx+C
1=3x-2+c
1=-6+c
c=7
y=3x+7
Answer:
The set of rigid motions could be used to show that triangle ABC is congruent to triangle DEF is " a horizontal translation and a vertical translation" ⇒ D
Step-by-step explanation:
- Horizontal translation means move the object right or left
- Vertical translation means move the object up or down
- Translation horizontally or vertically not change the direction of the object or its size, then the image is congruent to the original object
- Rotation and reflection change the direction of the object but do not change its size
∵ Δ DEF has the same direction as Δ ABC
∵ Δ DEF is congruent to Δ ABC
∴ The translation is using
∵ Δ DEF is right and below to Δ ABC
∴ There are horizontal and vertical translation
The set of rigid motions could be used to show that triangle ABC is congruent to triangle DEF is " a horizontal translation and a vertical translation"
