Input in stand form the equation of the given line.
Daniel [21]

Answer:

  3x +8y = -17

Step-by-step explanation:

The point-slope equation is a good place to start.

  y -k = m(x -h) . . . . . equation through (h, k) with slope m

Filling in your numbers gives ...

  y +4 = -3/8(x -5)

Multiplying by 8, we get

  8y + 32 = -3x + 15

Adding 3x-32 puts this in standard form.

  3x + 8y = -17

_____

Standard form is ...

  ax +by = c

where a, b, c are mutually-prime integers and the leading coefficient is positive. (If a=0, the leading coefficient is b.)

What is the length of segment AB?
AlekseyPX

Answer:

length of segment AB is 13

OR

AB = 13

Step-by-step explanation:

Use the Pythagorean Theorem with c being the length of segment AB.

a^2 + b^2 = c^2

5^2 + 12^2 = c^2

169 = c ^2 (square root both sides to get c by itself)

13 = c
