Find the slope of the line that passes through the points (9, -2) and (4, 3)

vovikov84 [41]

Answer:

-1

Step-by-step explanation:

Formula: $y=mx+b$

<u>Using two points:</u>

Since we are given the $y$ and $x$ value, what is left is the $m$ and $b$ in the formula, which represent slope and the y-intercept.

<u>Slope</u>

$m$ is slope

Formula: $\frac{y_2-y_1}{x_2-x_1}$

Plug points: $\frac{3-(-2)}{4-9}$

Solve: $\frac{5}{-5}$

Simplify: $\bold{m=-1}$

Therefore, the slope is -1

<u>y-intercept</u>

$b$ is the y-intercept

Plug one of the points and the slope into the formula, solve for b: (4, 3)

$3=-1(4)+b$

$3=-4+b$

$3+4=-4+b+4$

$\bold{b=7}$

A 2/3=8/2. B. 4/9=8/9 c 3/4>9/10 d 2/4>2/3 which comparison is true

vladimir2022 [97]

The given comparisons are not true in all of the options provided.

<u>Step-by-step explanation:</u>

The given comparisons are in the form of fractions.

Check each of the given options one by one based on the relation given for the comparison.

Option a) is 2/3 = 8/2. Here, you have to check that the given fractions are equal or not. If both the values are equal, then the comparison is true. If they are not equal, then the comparison is false.

By dividing 2 by 3, we get a value of 0.666

By dividing 8 by 2, we get a value of 4.

Therefore, 0.666 ≠ 4. The comparison is false.

Option b) is 4/9 = 8/9. Here, you have to check that the given fractions are equal or not.

Look into the given comparison, the fractions have same denominator of 9.

In such cases, if the denominator is same and the numerator value is different, then they are not equal.

Therefore, 4/9 ≠ 8/9. The comparison is false.

Option c) is 3/4 > 9/10. Here, you have to check whether 3/4 is greater than 9/10.

By dividing 3 by 4, we get a value of 0.75

By dividing 9 by 10, we get a value of 0.9

Therefore, 0.75 is not greater than 0.9. The comparison is false.

Option d) is 2/4 > 2/3. Here, you have to check whether 2/4 is greater than 2/3.

By dividing 2 by 4, we get a value of 0.5

By dividing 2 by 3, we get a value of 0.666

Therefore, 0.5 is not greater than 0.666. The comparison is false.

Marcie cooked dinner for herself. The original recipe has a serving size of 3 and requires three and three sevenths pounds of ch

Sati [7]

Using proportions, the number of pounds that will be needed for a single serving is: one and three seventh pounds.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.

The number of pounds for 3 people is given by:

$3 \frac{3}{7} = 3 + \frac{3}{7} = \frac{24}{7}$

Hence, for one person, the number of pounds can be divided by three(multiplied by 1/3), hence:

$\frac{24}{7} \times \frac{1}{3} = \frac{24}{21}$

24 divided by 21 has a quotient of 1 and remainder of 3, hence as a mixed number, the amount is:

one and three seventh pounds.
