How to find the slope of a line when given two points?

Mathematics

There is a slope formula for this.
slope = (y2 - y1) / (x2 - x1)

example : lets say u r given 2 sets of points....(1,2) and (3,4). First, we must label out points
set 1:  (1,2)....so lets label these : x1 = 1 and y1 = 2
set 2 : (3,4)...and we label these x2 = 3 and y2 = 4

now we sub these into our formula and solve
slope = (y2 - y1) / (x2 - x1)
slope = (4 - 2) / (3 - 1) = 2/2 = 1
so the slope of these 2 sets of points is 1.

one important thing to remember, ur points may not always be positive...so pay close attention to ur signs

On a blueprint, the scale indicates that 8 cm represent 16 feet. What is the length of a room that is 8.8 cm long and 3 cm wide
lana [24]
For the answer to the question above asking wWhat is the length of a room that is 8.8 cm long and 3 cm wide on the blueprint if <span>a blueprint, the scale indicates that 8 cm represent 16 feet?
</span>The room is 22.4 feet long

8cm=16ft
9.8cm=?ft

  8cm       9.8cm
______=______
  16ft          x ft

Cross multiply
8x=156.8
divide both sides by 8
x=19.6 ft

Equation for the points (3,8) (2,6) on slope
Irina18 [472]
\frac{8-6}{3-2} = \frac{2}{1}=4

The slope is 2

y=2x + b

Plug in a point to solve for b
8 = 2(3) + b

8 = 6 + b
b = 2

The equation is y = 2x + 2

Which figure best demonstrates the setup for the box method of finding the area of a triangle
Ivanshal [37]
Hi there! The third option shows us the best setup.

We can find the area of a triangle with the standard formula area = 1/2 * base * height.

To be able to fill in this formula, we need to have a base and a height. We can't easily find a triangle with given base and height, so we must look for another option.

We can also take the area of a square (length × width) and then divide the answer by 2. This is possible when we take the third setup. Hence the third answer is correct.

Write an equation in point-slope form of the line that passes through the point (9,0) and has a slope of m=-3 .
aksik [14]

Answer:

y =  - 3x + 27

Step-by-step explanation:

The standard form for the equation of the line is

y = mx + c

Recall that:

y = 0 \:  \:  \: x = 9 \:  \:  \: m =  - 3 \\ y = mx + c \\ 0 =  - 3(9) + c \\ 0 =  - 27+ c \\ 27 = c

Therefore the equation of the line is:

y = mx + c \\ y =  - 3x + 27
