Find the equation of a line which is perpendicular to y = 1/2x - 5 and goes throught the point (0, 0). Write your answer in the form y=mx+c.

y = -2x

Step-by-step explanation:

For a line to be perpendicular to another, it must have the opposite reciprocal slope.  In this case, that means 1/2 becomes -2/1 or -2.  For the line to pass through 0,0 the y intercept must be 0.  Thus the line is y = -2x + 0, or y = -2x

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.

your answer is a
