The line AB has midpoint (-2, 4).<br>A has coordinates (3,-2).<br>Find the coordinates of B.

worty [1.4K]

Answer: B(8, -8 )

Step-by-step explanation: The formula for calculating mid - point between two points is given as :

M = ( $\frac{x_{1}+x_{2}}{2}$ , $\frac{y_{1}+y_{2}}{2}$ )

The mid point has been given from the question .

$x_{1}$ = -2

$x_{2}$ = ?

$y_{1}$ = 4

$y_{2}$ = ?

substituting into the formula , we have

(3 , - 2 ) = ( $\frac{-2+x_{2}}{2}$ , $\frac{4+y_{2}}{2}$ )

Equating x -component to x and y component to y , we have

3 = $\frac{-2+x_{2}}{2}$

cross multiplying , we have

6 = -2 + $x_{2}$

Therefore:

$x_{2}$ = 8

Also , equating y component to y , we have

-2 = $\frac{4+y_{2}}{2}$

-4 = 4 + $y_{2}$

$y_{2}$ = -8

Therefore :

$x_{2}$ = 8

$y_{2}$ = -8

check

-2 + 8 / 2 = 3 and

-8 + 4 / 2 = -2

write an equation in slope-intercept form for the line parallel to y=-7x-9 that passes through the point (4,-9)

uranmaximum [27]

Answer:

7x = y + 37

Step-by-step explanation:

y = 7x - 9

Differentiating y with respect to x, we have as follows:

dy/dx = m = 7 ( where m is the slope)

Using the formula y - y1 = m(x - x1) to obtain the equation of line passing through point (4.-9)

y + 9 = 7(x - 4)

y + 9 = 7x - 28

∴ 7x = y + 37
