The point-slope form of the equation of the line that passes through (–5, –1) and (10, –7) is y plus 7 equals negative StartFrac
user100 [1]

Answer:

2x + 5y = - 15

Step-by-step explanation:

The line that passes through (–5, –1) and (10, –7) points and the point-slope form of the equation is y + 7 = - \frac{2}{5}(x - 10).

Now, we have to arrange this in the standard form.

So, y + 7 = - \frac{2}{5}(x - 10)

⇒ 5(y + 7) = - 2(x - 10)

⇒ 5y + 35 = - 2x + 20

⇒ 2x + 5y = - 15 (Answer)

The midpoint of AB is M(1, 3). If the coordinates of A are(4,1), what are the coordinates of B?
Oxana [17]

Answer:

B(-2,5)

Step-by-step explanation:

\frac{x + 4}{2}  = 1 \\ 2 \times  \frac{x + 4}{2}  = 1 \times 2 \\ x + 4 = 2 \\ x = 2 - 4 \\ x =  - 2 \\  \frac{y + 1}{2}  = 3 \\ 2 \times  \frac{y + 1}{2}  = 3 \times 2 \\ y + 1 = 6 \\ y = 6  -  1 \\ y = 5

Hope that this is helpful.

Have a nice day.
