Answer:
S(-7,0) , 2/7
Step-by-step explanation:
To get coordinates of P we can see that
14*(2/7)=4
Now, to get coordinates of S, we have this equation :

Multiply by 7 each side :
2x=-14
x=-7
y=0
The slope is (8-2)/(0-2)=-3
the y intercept is 8
the equation is y=-3x+8
the area to the left is shaded, and the line is solid, so y

-3x+8
The 3 angles of a triangle, when added, = 180 degrees
so if 2 of them are 70.....70 + 70 = 140
then the 3rd will be 180 - 140 = 40 degrees <==
