The slope, m, of a linear equation can be found using the formula m = StartFraction y 2 minus y a Over x 2 minus x 1 EndFraction
Otrada [13]

Answer:

Please check the explanation.

Step-by-step explanation:

Given the points

  • (x₁, y₁)
  • (x₂, y₂)

Using the formula  to determine the slope between (x₁, y₁) and (x₂, y₂) of the linear function

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]

For example, let the points be

(x₁, y₁) = (1, 2)

(x₂, y₂) = (3, 4)

Determining the slope between

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]

               =  [4 - 2] / [3 - 1]

               = 2 / 2

               = 1

Thus,

The slope of the line between the points (1, 2)  and (3, 4)  will be: m = 1

Please help!!! I really don’t get this only I get where the 3 are but please help me for the 4/5 and -0.4!
Naily [24]

Answer:

-0.4 should be in between 0 and -0.5, however be as close to -0.5 as possible while not being ON -0.5.

3 4/5 should be in between 3 and 4, so you can split 4/5 into 8/10 which are equal to each other. Then you can pretend to split the 3 and 4 gap into 10 equal pieces. After you split the gap, count 8 parts to the left of 3.

Step-by-step explanation:

I hope you understand what I mean.

Which of the following lines has a zero slope?
Pavlova-9 [17]

It should be A because C cannot exist at the moment. B and D are clearly slopes, so it has to be A.

In Figure 1, the area of square A is 9 square units, the area of square B is 16 square units, and the area of square C is 25 squ
weqwewe [10]

Answer:

C. The sum of the areas of the two smaller squares is equal to the area of the larger square.

Step-by-step explanation:

9 + 16 = 25

36 + 64 = 100

25 + 144 = 169

The relations "less than" and "greater than" can be ruled out. These observations are consistent with selection C.

The triangle area is half the product of the square roots of the squares on the legs, so the areas of the triangles are (respectively) 6, 24, 30. These are not related to the sum of the smaller squares, so the last selection can also be ruled out.

If f(x) = 3x - 2 and g(x) = 2x + 1, find (f - g)(x)
morpeh [17]

Answer:

(f-g)(x) = x-3

Step-by-step explanation:

Given

f(x) = 3x-2

and

g(x) = 2x+1

We have to find (f-g)(x)

So,

(f-g)(x) = f(x)-g(x)

= 3x-2 - (2x+1)

= 3x-2-2x-1

=x-3

Hence,

(f-g)(x) = x-3
