Focus on triangles DFC and DFE:
- They are both right triangles because DF is perpendicular to EC
- DC=DE
- DF is a common side
So, the two triangles are congruent. It follows that CF=FE, and in particular

And since x=3, the length of EF is

Answer:
Take the slopes, such that 7-4/-4+3= 3/-1=-3
So one endpoijt is (-5,10)
Answer:
y = 3x + 13
Step-by-step explanation:
Here, we want to solve for y
To solve for y, we simply are going to make y the subject of the formula
We have this as;
y - 3x = 13
y = 13 + 3x
