Answer:

Step-by-step explanation:

To find y=mx+b we need to identify two points. I picked (20,45) and (50,65)

From these two points we can find the slope, m.

m=(y2-y1)/(x2-x1)

m=(65-45)/(50-20)

m=20/30=2/3 so now our line is

y=2x/3+b, we can solve for b using either point, I’ll use (20,45)

45=2(20)/3+b

45=40/3+b

b=45-40/3

b=(135-40)/3

b=95/3 so the line is

y=(2x+95)/3

Answer:

$x=\frac{\pi}{2}$ and $x=\frac{3\pi}{2}$

Step-by-step explanation:

We need to solve the 2 equations to figure out the x-values (intersecting points).

<em>Note: </em>The identity $cos^{2}x=\frac{1}{2}+\frac{1}{2}cos(2x)$

$cos(2x)=cos^{2}(x)-1\\cos(2x)=(\frac{1}{2}+\frac{1}{2}cos(2x))-1\\cos(2x)=\frac{1}{2}cos(2x)-\frac{1}{2}\\\frac{1}{2}cos(2x)=-\frac{1}{2}\\cos(2x)=-1\\2x=cos^{-1}(-1)\\2x=\pi, 3\pi\\x=\frac{\pi}{2}, \frac{3\pi}{2}$
