What is the equation of the line shown in this graph

y=-2x+4

Step-by-step explanation:

The equation of the line is:

y=mx+b

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

we have two points giver from the graph:

point 1: (1,2)

point 2: (4,-4)

we to find the slope:

m=(-4-2)/(4-1)

m=-6/3

m=-2

we need to find "b"

using the point (1,2)

we have:

2=-2*(1)+b  

2=-2+b

so we have b=2+2=4

finally we have that the answer is:  

y=-2x+4

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.

step-by-step explanation:

a rhombus is a parallelogram enjoying his symmetry.
