Standard form looks like this: Ax + By = C.
y - (-1) = 3(x - 4)
y + 1 = 3x - 12
y = 3x - 12 - 1
y = 3x + 13
Move 13 to left side and y to right side.
-13 = 3x - y
Done!

Step-by-step explanation:
It'll be an acute angle, because a right angle would've been 90° but it's 89°. An obtuse angle would've been over 90°.
The answer is 4/5=0.8
the method;
(y1-y2)/(x1-x2) which is (6-2)/(-4-(-9))
=4/5 =0.8
