Answer:

B(5, 4)

Step-by-step explanation:

The midpoint formula is ...

M = (A +B)/2

Solving for B gives ...

B = 2M -A

B = 2(1, -2) -(-3, -8) = (2+3, -4+8) = (5, 4)

The coordinates of B are (5, 4).

Find the equation of the line through the points (-2,5) and (3,-10). Give your answer in slope-intercept form.

$m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}} = \frac{-10 - 5}{3 - (-2)} = \frac{-15}{3 + 2} = \frac{-15}{5} = -3$

y - y₁ = m(x - x₁)
y - 5 = -3(x - (-2))
y - 5 = -3(x + 2)
y - 5 = -3(x) - 3(2)
y - 5 = -3x - 6
+ 5 + 5
y = -3x - 1
