Cot A=1/tan A=12/5
cos A= 12/13
sin A=5/13
Draw a right angled triangle
the hypotenuse is the longest side which is 13 using Pythagoras theorem
the side opposite the angle A is 5
the side closest to the angle A which is called the adjacent is 12
sinA =opp/hyp
cos A= adj/hyp
cotA =1/tanA=cos A/sinA
Note: Pythagoras theorem is
hyp²=opp²+adj²
You find the slope-intercept form by simplifying the point-slope equation.
Slope-intercept formula: y = mx + b where m = slope and b = y-intercept
Observe.
y - 3 = 1(x - 1)
y - 3 = x - 1
+3 + 3
y = x + 2 <----------------SI form = Answer
