Answer:

\frac{15}{17}

Step-by-step explanation:

  • \cos( \alpha )  =  \frac{ad}{hip}  \\  \\  \sin( \alpha )  =  \frac{op}{hip}

Pythagorean theorem

hip² = op² + ad²

17² = x² + 8²

x² = 17² - 8²

x \:  =  \sqrt{{17}^{2}  -  {8}^{2} }  \\ x =  \sqrt{289 - 64}  \\ x =  \sqrt{225}  \\ x = 15

\sin( \alpha )  =   - \frac{15}{17}

\sin( -  \alpha )  =  \frac{15}{17}

I need help with this, I've never really understood linear stuff.
KonstantinChe [14]

You have several possible points (x,y). Any point that lies on the given line will have a y value that you obtain by plugging in the corresponding value of x into the equation of the line.

The line has equation y=-3x+7, so any point on the line will have the form (x,-3x+7).

Among the four given points, there are only 2 different values of x to check. We have

x=4\implies y=-3(4)+7=-12+7=-5

x=1\implies y=-3(1)+7=-3+7=4

which means the given line contains the points (4, -5) and (1, 4). So the answer is A.
