Cd is perpendicular to ab and passes through point c(5, 12). if the coordinates of a and b are (-10, -3) and (7, 14), respectively, the x-intercept of cd is . the point lies on cd . blank one 1)12,0 2)15,0 3)17,0 4)19,0 blank two 1)-5,24 2)-2,19 3)7,-10 4)8,11

First blank (17,0)

Option 3 is correct

Second Blank (-2,19)

Option 2 is correct  

Step-by-step explanation:

CD is perpendicular to AB

C(5,12)

A(-10,-3)

B(7,14)

CD ⊥ AB

Thus, Slope of CD is negative inverse of slope of AB

Slope of CD, m=-1  (CD ⊥ AB )

Point C: (5,12)

Equation of line CD,

For x-intercept: Put y=0

x-intercept: (17,0)

For second blank we have to check each point.

Option 1: (-5,24) ,Put x=-5 and y=24

False

Option 2: (-2,19) ,Put x=-2 and y=19

True

Option 3: (7,-10) ,Put x=7 and y=-10

False

Option 4: (8,11) ,Put x=8 and y=11

False

Hence, First blank (17,0) and Second blank (-2,19)

it would rotate about 180 degrees.
