Answer:
Helena is correct.
Step-by-step explanation:
The slope intersept form of the line is
y = m x + c
where, m is the slope and c is the intersept.
The point slope form of the equation is

So, if there are two points are given, the equation of line is found by the point slope form.
So, Helena is correct.

Answer:
Step-by-step explanation:
it's 2ab + c^ 2
why?, well, we can change the position of the 2 triangle in each corners into this (in the picture below) :
you can see that a^2 + b^2 = c^2
then there are 2 ab from 4 triangles we add that create 2 rectangle then we multiply each rectangles by its sides
so , c^ 2+ 2ab is the answer
I
hope this is helpul!
