The picture in the attached figure

we have
arc XV = 68°∠YUV = 36°
we know that
The measure of the external angle is the semidifference of the arcs that it covers.
therefore
∠YUV =[arc VY-arc XV]/2

arc VY=[2*∠YUV]+arc XV----------> [2*36]+68---------> 140°

the answer is
the measure of arc VY is 140°

Graph the line that has a slope of 1/4 and includes the point (0,8)

Alex787 [66]

Step-by-step explanation:

Equation of line:

$y = mx + c$

where m is the slope

and c is the y-intercept (the value of y when x = 0)

In this case, given the slope = 1/4

and y-intercept is 8 (from the point (0,8))

The equation of the following line is:

$y = \frac{1}{4} x + 8$
