Answer:

y = 9x - 15

Step-by-step explanation:

The given y = 9x - 5 is already in slope-intercept form. Any line parallel to this one has an equation that looks exactly the same except for the constant term. Call the new constant term 'C.'

Start with y = 9x - 5 and substitute the coordinates of the given point (-1, 6):

6 = 9(-1) + C, or

6 + 9 = C, or

C = 15

Then the equation of the line that passes through (-1, 6) and is parallel to y = 9x - 5 is

y = 9x - 15

What is the distance from X to Y?

Rama09 [41]

Answer:

Step-by-step explanation:

To find the distance between two points, $(A, B)$ and $(C, D)$ , you can use the following distance formula:

$distance = \sqrt{(A - C)^{2} + (B - D)^{2}}$

Plugging in the points from the problem, you'll get the following:

$\sqrt{(0 - 9)^{2} + (6 - (-6))^{2}}$

$\sqrt{(-9)^{2} + (12)^{2}}$

$\sqrt{81 + 144}$

$\sqrt{225}$

$15$
