Write the equation of a line that goes through (5,3) and is parallel to the line y=2x+7

y = 2x - 7

Step-by-step explanation:

Parallel lines have the same slope, so the line will also have a slope of 2

Plug in the slope and given point into y = mx + b to solve for b:

y = mx + b

3 = 2(5) + b

3 = 10 + b

-7 = b

Then, plug in the slope and b into y = mx + b

y = 2x - 7 is the equation of the line

D. 39

you use the pythagorean theorem which is

if you look at the triangle we can see that we have to find the length of the hypotenuse (BC).

so your equation will look like this:  

1.      (solve for )

2. C= 225+1296      (add)

3.  C= 1521               (find the square root of 1521)

4.

Therefore, 39 is your answer

Hope this helps!
