The slope-intercept equation is y=mx+b.

The slope formula is $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

Our three points are (5,5), (-5,-7) and (0,-1)

Using our slope formula our slope becomes $\frac{-7-5}{-5-5} =\frac{12}{10} =\frac{6}{5}$

Then, if we use one of our points (pick whichever you want, although (0,1) is the easiest) to solve the equation. So, $y=\frac{6}{5}x-1$ . When we solve for x and y, we get -1=0+b, or b=-1.

When we plug that back into the equation, we get $y=\frac{6}{5}x-1$ .

Prove that if b is a square matrix then b+b^t is symmetric

WARRIOR [948]

A matrix $\mathbf X$ is symmetric if $\mathbf X=\mathbf X^\top$ . We have

$(\mathbf B+\mathbf B^\top)^\top=\mathbf B^\top+(\mathbf B^\top)^\top=\mathbf B^\top+\mathbf B=\mathbf B+\mathbf B^\top$

and so $\mathbf B+\mathbf B^\top$ is indeed symmetric.
