Step-by-step explanation:
Hi there!
<u>What we know</u>:
The line goes through the points (-8,-8) and (-7,9) We need to write the equation of the line in point-slope form <u>What we need to know:</u>
Point-slope form: where m is the slope of the line and is a point that the line passes through We're given " ", which is the " " part of the point-slope form equation. This means that is and we only need to solve for m.
Our equation so far (plugging in the point (-7,9):
<u>Determine the slope (m)</u>
where two points are and
Plug in the given points (-8,-8) and (-7,9)
Therefore, the slope of the line is 17. Plug this into :
I hope this helps!

Step-by-step explanation:
sin^2x=1/2
so sinx=1/V2=V2/2
x=pi/4
