Given points F(3,1), G(5,2) H(2,4), and J(1,6)
Karo-lina-s [1.5K]

The slopes of perpendicular lines are opposite reciprocals

The true statement is that segments FG and HJ are perpendicular

<h3>How to determine the relationship between the segments</h3>

The coordinates of the points are given as:

F = (3,1)

G = (5,2)

H = (2,4)

J = (1,6)

Start by calculating the slopes of FG and HJ using the following slope formula

m = \frac{y_2 -y_1}{x_2 -x_1}

So, we have:

FG = \frac{2 -1}{5 -3}

FG = \frac{1}{2}

Also, we have:

HJ = \frac{6 - 4}{1 - 2}

HJ = \frac{2}{-1}

HJ = -2

To determine the relationship, we make use of the following highlights

  • Parallel lines have the same slope
  • The slopes of perpendicular lines are opposite reciprocals

From the computation above, we have:

  • The slopes of both lines are not equal
  • The slopes are opposite reciprocals i.e. 2 = -1(-1/2)

Hence, segment FG and HJ are perpendicular

Find the distance between the points with coordinates (-26,0) and (95, 0).
mote1985 [20]

Answer:

0

Step-by-step explanation:

Distance between two points is the slope .

Slope =change in y/change in x

Given (-26,0) and (95,0)

x1 = -26

y1 = 0

x2 = 95

y2 = 0

Slope = y2 - y1 / x2 - x1

0-0/95-(-26)

0-0/95+26

0/121

(3h-2m)(2h+m) multiple
den301095 [7]
If you want to multiply 2 binomials, take each term in the first set of parentheses and multiply it to every term in the second set of parentheses:
3h*(2h+m) = 3h^2+3hm
-2m*(2h+m) = -4hm-2m^2
Combine like terms: (3hm-4hm)
3h^2-hm-2m^2
