Type the correct answer in each box. if necessary, use / for the fraction bar(s). given: ab || cd . if the coordinates of point a are (8 , 0) and the coordinates of point b are (3 , 7), the y-intercept of ab is . if the coordinates of point d are (5 , 5), the equation of line cd is y = x + .

1. 11.2

2. -1.4

3. 12

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
