<span>As we know
cos theta-1= 0 
 cos theta = 1
  Now Look at a graph of the cosine function
, and you will observe that cos theta = 1
 at the points X = 0, and X = 2pi
hope it helps</span>

Write the slope e-intercept from of the equation of the line through the given point with the given slope. Please show your work
Zinaida [17]
The slope-intercept form is written under the form of
y=mx+b where m represent the slope and y represent y-intercept. In this case, we know that the m is 8, but we don't have b yet. To find the answer, substitute (0,5) into an equation where y=5 and x=0
y=mx+b
y=8x+b
5=8(0)+b
5=b, so we have the complete y-intercept form which is y=8x+b
Or
You can you this
y-y1=m(x-x1) where point (x1,y1) represent point (0,5) in this case which led to:
y-y1=m(x-x1)
y-5=8(x-0)
y-5=8x-8(0)
y-5=8x
Add 5 to each side
y-5+5=8x+5
y=8x+5 represent the slope-intercept form. Hope it help!
