Hello,
y+2=1/3*(x-1) ==>3y+6=x-1==>x-3y-7=0
Answer C
I think you can the is an app that can help with graphing its called desmos
DBH make a triangle.
The three inside angles of a triangle need to equal 180
H = 180 - B - D
H = 180 - 39 - 36 = 105
H and X make a straight line that equals 180 degrees
X = 180 - H
X = 180 - 105 = 75 degrees.
