Point slope graph y+2÷4(x+5)
ladessa [460]

Answer:

See attachment for graph

Or

The slope intercept form is y=4x+18

Step-by-step explanation:

Assuming you want to graph the straight line given in point-slope form as

y+2=4(x+5)

Then we need at least two points on this line

When we compare to the point-slope formula y-y_1=m(x-x_1) then we  obtain (-5,-2) as a point on this line so we plot it.

When x=0, y=4(0+5)-2=18 so we plot (0,18)

We then draw a straight line through as shown in the attachment.

On the other hand, if you had wanted the equation slope intercept form, then we expand to obtain:

y+2=4x+20

\implies y=4x+20-2

\implies y=4x+18

Simplify sinø + cosø × cotø
insens350 [35]
That would be 
                        cos x
sin x + cos x * --------
                        sin x
               
                        sin x
Mult sin x by ----------
                        sin x

to obtain 

(sin x)^2
------------
   sin x

and then add

(cos x)^2
-------------
   sin x

with the outcome being 

(sin x)^2 + (cos x)^2        1
--------------------------- = --------- = cos x (answer)
              sin x                sin x
