Answer: look at pic
Step-by-step explanation:
y=mx+b
m:slope
b:y-intercept
m=-1 (slope) given in the question
y=-1x+b
Plug in the given point (-1,-4) then solve for b
-4=-1(-1)+b
b=-5
y=-x-5
then using the x-intercept and y-intercept you could graph the line
y-intercept = b = -5 (0,-5)
x-intercept (plug in y=0)
0=-x-5
x=-5 (-5,0)
Step-by-step explanation:
see the answer in the pic
u must prove that
Cotx/1+cscx=1-cscx/cotx
cuz that's the way
