Can someone help me with part B

Answer 1

okay so slope intercept form is

y = m(x)+b

where m is the slope and b is the y intercept the point on the graph where it crosses the y axis when x = 0.

Answer 2

I got y=-1/2x+?

Answer 3

\[y-13 = -\frac{ 1 }{ 2 }(x-6)\]

okay so first step we've gotta distribute the -1/2

\[-\frac{ 1 }{ 2 }x-(-\frac{ 1 }{ 2 }*6) = -\frac{ 1 }{ 2 }x+3\]

Answer 4
