Answer:

Yes

Step-by-step explanation:

If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.

Choose the point slope form of the equation below that represents the line that passes through the points (-3, 2) and (2, 1)

mihalych1998 [28]

Answer:

$\large\boxed{y-1=-\dfrac{1}{5}(x-2)}$

Step-by-step explanation:

The point-slope form of a line:

$y-y_1=m(x-x_1)$

m - slope

(x₁, y₁) - point

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (-3, 2) and (2, 1). Substitute:

$m=\dfrac{1-2}{2-(-3)}=\dfrac{-1}{5}=-\dfrac{1}{5}$

$y-1=-\dfrac{1}{5}(x-2)$

Do 3/7and7/3 represent the same length on a number line?

Fudgin [204]

Nope. 3/7 is less than 7/3. 7/3 in mixed numbers form is 2 1/3. Therefore, we will have different lengths where 3/7 will be smaller than 7/3.
