In a triangle there are three angle.So, the side opposite to the greatest angle will be greatest side in the triangle and hence it will be the slope of the triangle.
you can find slope of any side of the triangle by finding tangent of the angle made by it to the horizontal side
eg. place one side of the triangle horizontally. to find the slope of any side A, drop a normal from the apex to intersect the imaginary horizontal line.measure the length(l1) of the normal. measure the distance (l2) between the intersecting point and other end of side A. l1/l2 will give you the slope of side A.

For triangle ABC, find the midpoint of side BC. Then, find the slope of side BC and use its negative reciprocal (since the negative reciprocal slope is the slope of the right bisector joining side BC and the opposite vertex). Finally, substitute the midpoint and negative reciprocal slope into the y=mx+b equation to get "b", then write the equation. :)
They have to be across from each otherJoin the equationsSolveYou will know if you got it right if your slope is the same for both sides
Draw a line of best fit through the plotted points which will give the y intercept. Draw a right angle triangle under the line which will be the triangles hypotenuse. Divide the vertical units of the triangle by the horizontal units which will give the value of the slope.
All this represents is the angle of a triangle, which is calculated using trigonometry. The slope is given in degrees of an angle.
The slope can be a fraction.
