Right angles are 90 degrees
acute angles are less than 90 degrees
obtuse angles are greater than 90 but less than 180

An acute angle is less than 90 but more than zero typically 54 degrees
an obtuse angle is more than 90 but less than 180 typically 112 degrees
a right angle is 90 degrees

Write an equation in point-slope form, y – y1 = m(x – x1), of the line through points (9, –2) and (10, 2). Use (9, –2) as the po

$\bf \begin{array}{ccccccccc}

% slope = m
slope = m\implies 
\cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{2-(-2)}{10-9}\implies \cfrac{2+2}{10-9}\implies \cfrac{4}{1}\implies 4

% point-slope intercept
\stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}\implies y-(-2)=4(x-9)\implies y+2=4(x-9)$
