Step-by-step explanation: hope it helps
To find slope you need to use the coordinates of two points on the line. If the coordinates are (x1, y1) and (x2, y2) do y2-y1 / x2-x1 to find the slope.
So far in the equation of a line, y=mx+b, you have the "m" which is the slope.
Plug in the slope, and the x and y values from one of the points and solve for b, which is the y intercept.
Here's an example if the coordinates are (1,4) and (2,6):
6-4/2-1 = 2/1 = 2
The slope is 2.
y = 2x + b
4 = 2(1) + b
4 = 2 + b
4-2 = 2-2 + b
2= b
The full equation is y = 2x + 2
to find the coordinates you'll need the cos and sin of the angle its just like with x and y:
(x,y)= (cos angle, sin angle)
to find the sin, you simply need to use these formulas:
sin² A + cos ² A= 1
sin A/ cos A= tan A
1.
sin² O + cos² O= 1
sin²O= 1- cos² O
sin²O= 1- (-9/41)²
sin²O= 1600/1681
sin O= V1600/ V1681
sin O= 40/41
2.
sin O/ cos O = tan O
(40/41)/(-9/41)= tan O
-164/9= tan O
