Answer:
Step-by-step explanation:
step 1
Write an equation in point-slope of the line passing through point A and parallel to line B
Remember that
If two lines are parallel, then their slopes are equal
In this problem the slope of the given line is m=2
That means
The slope of the parallel line is also m=2
we have
substitute
step 2
Convert to slope intercept form
isolate the variable y
The answer is C.
Answer: 5
Using the options use the Pythagorean theorem
5^ 2 + 12^2 = 25 + 144 = 169
Sqrt(169) = 13
8 + 5 = 13
answer: t = 5
