If a line goes through points (-2, 9) and (0, 3), what is its slope? 3 -3 6 -1/3

Scrat [10]

Answer:

The slope of a line is:

$m=-3$

Hence, option B is true.

Step-by-step explanation:

Given the points

(-2, 9)

(0, 3)

Finding the slope between (-2, 9) and (0, 3)

$\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$

$\left(x_1,\:y_1\right)=\left(-2,\:9\right),\:\left(x_2,\:y_2\right)=\left(0,\:3\right)$

$m=\frac{3-9}{0-\left(-2\right)}$

$m=-3$

Therefore, the slope of a line is:

$m=-3$

Hence, option B is true.

Write the equation 0.3x2 + 5x - 7 =0 in general form and then choose the value of "b."

Musya8 [376]

For this case we have that by definition, an equation of the second degree is given by:

$ax ^ 2 + bx + c = 0$

We have the following equation:

$0.3x ^ 2 + 5x-7 = 0$

Then, according to the definition above, we have to:

$a = 0.3\\b = 5\\c = -7$

Thus, b equals 5.

Answer:

$b = 5$

Option C

Change 7 3/8 from a mixed. number to to an improper fraction

ASHA 777 [7]

First, we set up the mixed number 7 3/8 with different colors, so it is easy to follow along:

7
3
8

Step 2 - Multiply
Next, we multiply the whole number by the denominator.

7 x 8 = 56

Step 3 - Add Numerator
Then, we add the numerator to the answer we got in Step 2.

56 + 3 = 59

Step 4 - Solution
Finally, to get the solution, we keep the original denominator and make the numerator the answer from Step 3. Thus, 7 3/8 as an improper fraction is:

59
8
