Use the point-slope formula for the eqn of a str line:
y-1 = 2(x-1)
This becomes y = 1+2(x-1) = 1 + 2x - 2 = 2x - 1,
so the simplest form of the desired eqn is y = 2x - 1.

Answer:
-24/5
Step-by-step explanation:
The solution to the problem is as follows:
cscx < 0 means 1/sinx < 0, or sinx < 0.
sinx = -3/5 because you're dealing with a 3-4-5 triangle, and we established
sinx is negative.
sin2x = 2sinxcosx = 2*-3/5*4/5 = -24/25
cos(2x) = cos^2(x) - sin^2(x) = 16/25 - 9/25 = 5/25 = 1/5
tan2x = sin2x / cos2x = -24/5

Answer: (-2,4)
Step-by-step explanation:
When you go up any number of units, you add it to the y-coordinate. So -3 + 7 = 4. That would make it, (2,4). The next step would be reflecting it across the y-axis. And whenever you reflect across the y-axis, the x-coordinate always changes.
