I think it is the third one necause......
Hello,
(6x+13)+(3x-4)=180
9x+9=180
9x=171
x=19
angle QRS measures 3x-4=3*19-4=53(°)
Answer:
The y-intercept of line is (-3)
Step-by-step explanation:
Given equation of line is given by y= 
The general equation of line is given y=mx+c
Where, m= slope of line
c= y-intercept of line
On comparing both the equation.
c=(-3)
OR
y-intercept is when x=0,
therefore,
y= 
y= 
y=(-3)
Thus, y-intercept of line is (-3)
