Answer:

m=-\frac{8}{5}

Step-by-step explanation:

Let

A(-1,4),B(4,-4)

we know that

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

substitute the values

m=\frac{-4-4}{4+1}

m=\frac{-8}{5}

m=-\frac{8}{5}

Answer: -\frac{8}{5}

Remember: RISE/RUN (y/x). Lines that are increasing have a positive slope, and lines that are decreasing have a negative slope.

You can find the slope in two ways:

1. Useful if the line is graphed: count the units between 2 points on the line.

  • Let's use the points (-1, 4) and (4, -4).
  • (-1, 4) is 8 units higher than (4, -4) and 5 units to the left of (4, -4).
  • Because the line is decreasing, the slope is negative.
  • Therefore, the slope is -\frac{8}{5}.

2. Useful if the line is not graphed: find the difference between the y-coordinate values divided by the difference of the x-coordinate values.

  • Let's use the points (-1, 4) and (4, -4).
  • \frac{-4 - 4}{4 - (-1)} = \frac{-8}{5}
  • Therefore, the slope is -\frac{8}{5}.

Which one of the following formulas correctly expresses this statement: A quantity x is equal to the sum of the squares of a and
Anit [1.1K]

Answer:

The correct option is D.

Step-by-step explanation:

We have to find the expresses this statement: A quantity x is equal to the sum of the squares of a and b.

The square of a can be written as a² and the square of b can be written as b².

The sum of squares of a and b can be written as

a^2+b^2

Since the quantity x is equal to the sum of the squares of a and b, therefore

x=a^2+b^2

Therefore option D is correct.

In triangle HJK shown above what is the measure of ∠J in degrees
ludmilkaskok [199]

Angles in a triangle adds up to 180

180 - (25.5 +120.2) = 34.3

So, missing angle is 34.3 degrees

Hope this helps!
