Please help i’ll give brainliest if you give a correct answer and show your work!

Determine whether the graphs of y=8x+5 and -y=8x-5 are parallel, perpendicular, coincident, or none of these. a. coincident b. parallel c. perpendicular d. none of these

What is the equation of the line in point-slope form? y+ 4 = 1/2(x+4) y-4 = 1/2(x + 4) y-0 = 2(x - 4) y-4 = 2(8-0)

Can someone me with #s 8, 9, and 11. with just one of the three also works. prove using only trig identities.
