Answer:
Step-by-step explanation:
The slope intercept form is .
The "" is the slope; which in this case is -3. So
.
The "" is the y-intercept, which is this case is the -8 because it is the 2nd number in the coordinate point.
This is why the answer is .
Answer:
OD = 9.375"
Step-by-step explanation:
We can draw a line from O to B to create a triangle.
Then, Triangle ODB and Triangle ACB are similar, so their corresponding side's ratio are similar as well.
Triangle ACB, we can use pythagorean theorem to figure out CB:
AC^2 + CB^2 = AB^2
15^2 + CB^2 = 17^2
225 + CB^2 = 289
CB^2 = 64
CB = 8
Now relating the corresponding sides, we can figure out OD:
