Question

what is the equation of a line which includes points (1,1) and (1,5)?

Answer 1

First find the slope using this formula:
\[m=\frac{y _{2}-y _{1}}{x _{2}-x _{1}}\]

Answer 2

Having found the slope, plug it and one of the points into the point-slope formula:
\[y-y _{1}=m(x-x _{1})\]

Answer 3

Then rearrange the equation so that it says y =
