vesna_86 [32]
<h2>SOLVING</h2>

\Large\maltese\underline{\textsf{A. \space What is Asked}}

Find the gradient of the line segment between the points \bf{(4,3)\:and\:(5,6)}

\Large\maltese\underline{\textsf{B. This problem has been solved!}}

The formula used, here is

\bf{m=\dfrac{y2-y1}{x2-x1}

\cline{1-2}

Now let's put in the co-ordinates from these two points.

\bf{m=\dfrac{6-3}{5-4}} | subtract on top & bottom

\bf{m=\dfrac{3}{1}} | divide

\bf{m=3}

\cline{1-2}

\bf{Result:}

                      \bf{=m=3}

\boxed{\bf{ aesthetic\not101}}
