Find the midpoint of the line segment joining the two points.<br> (1.8, -3.4) and (-0.4, 1.4)

murzikaleks [220]

Answer:

(0.7, -1)

Step-by-step explanation:

To find the coordinates for the midpoint you add each coordinate together and divide by 2.

M = ( $\frac{1.8 - 0.4}{2}, \frac{-3.4 + 1.4}{2}$ )

M = $(\frac{1.4}{2}, \frac{-2}{2})$

M = (0.7, -1)

A line passes through (8,2) and (11,-13) write the equation of thr line in standerd form

docker41 [41]

Answer:

Step-by-step explanation:

(8,2),(11,-13)

slope(m) = (-13 - 2) / (11 - 8) = -15/3 = -5

y = mx + b

slope(m) = -5

(8,2)...x = 8 and y = 2

now we sub and find b, the y int

2 = -5(8) + b

2 = -40 + b

2 + 40 = b

42 = b

so ur equation is : y = -5x + 42...now we need it in standard form

Ax + By = C

y = -5x 42

5x + y = 42 <====
