C can be -8 or 16 and the value of m is 2
The slope is 9
You use the formula y=mx+b and plug in the y and x from the chart. I’m not 100% sure cuz I did this 3 years ago so sorry if it’s wrong!
To find x you have to put ~ 25+x+15=3x-10 ~ once you have solved for x, you plug it in ~x+15 and once you have that angle do the same to fro letter C and than find the measure for D the same way
i hope this was help
