50/x = 42 / 63
x = 50 * 63 / 42
x = 75
1. 11/(11+JG)=20/50
11+JG=27.5
JG=16.5
2. i still need some time.. is triangle RST a right-angled triangle or not?
The formula for point slope form is (y-y1) = m(x - x1)
In this formula m will always be the slope. So, you can substitute 3 in for m
(y-y1) = 3(x-x1)
y1 is the y-coordinate and x1 is the x-coordinate. So, you can substitute them in and you will be done.
(y - 1) = 3(x - (-2))
But since it is minus a negative it changes to a positive so it would be:
(y -1) = 3(x + 2)
Hope this helps!
