Step-by-step explanation:
The equation of the line that passes through the points A(8,0) and B(3,7) is

To find the y-intercept, plug into this equation x=0:

Two parallel lines have the same slope, so the equation of the line CD is

This line passes through the point D(5,5), thus

Hence, the equation of CD is

Answer:
1/2
Step-by-step explanation:
There are 6 sides on a number cube, each labeled with 1,2,3,4,5, and 6.
Out of these, 2,3, and 5 are odd numbers. That's 3.
Probability is the (number of ways the event can occur)/(total number of possible outcomes)
So 3/6=1/2
