Plug them into point-slope form.

y - y1 = m(x - x1)

Where y1 is the y-value of the point, x1 is the x-value, and 'm' is the slope.

Plug in what we know:

y - 4 = -5(x + 2)

So one of our answers is C.

Now distribute -5 into the parenthesis:

y - 4 = -5x - 10

Add 4 to both sides:

y = -5x - 6

Add 5x to both sides:

5x + y = -6

So the other answer is B.

Which equation is a point-slope form of the equation of this line (-2, 1 ) and (1, 7 )
lana [24]

The point-slope formula:

y-y_1=m(x-x_1)\\\\m=\dfrac{y_2-y_1}{x_2-x_1}

We have (-2, 1) and (1, 7).

Substitute:

m=\dfrac{7-1}{1-(-2)}=\dfrac{6}{3}=2

y-1=2(x-(-2))\\\\y-1=2(x+2)

18,19,20,21,23 please help me. I really need this answer.please help me.

Answer:

18. Supplementary

19. Vertical

20. x = 7

23. x = 25

Step-by-step explanation:

Use angle relationships to make equations which you can solve for x.

Example:

18. These two angles form a line. These are called supplementary.

19. These angles are across a vertex from each other and are equal or the same.

20. 9x + 1 = 7x - 9 + 5x - 11

9x + 1 = 12x - 20

9x - 9x + 1 = 12x - 9x - 20

              1 = 3x - 20

      1 + 20 = 3x - 20 + 20

            21 = 3x

              7 = x

23. These two angles are across a vertex from each other. This means the angles are equal. Think of it as a reflection. If you folded the paper on that vertex, the lines would be in the exact same place.

So set the two expressions equal to each other. Then use inverse operations to isolate x and solve.

5x + 4 = 8x - 71

5x - 5x + 4 = 8x - 5x - 71

4 = 3x - 71

4 + 71 = 3x - 71 + 71

75 = 3x

25 = x

For breakfast, Clarissa can choose from oatmeal, cereal, French toast, or scrambled eggs. She thinks that if she selects a break
makvit [3.9K]

Clarissa is not correct. If she were to choose one from the stack at random, it means that she has a 25%, or a 1/4 chance to pick the oatmeal, just like the other breakfast items.

If there were to be more oatmeals than any of the other items, it will heighten the chance of her getting oatmeal which would be the only way to make her statement correct.
