Answer:

$y+9 = - 9x +18$

Step-by-step explanation:

Line is passing through the point $(2,\: - 9) =(x_1,\:y_1)$ and has slope (m) = - 9

General equation of line in point slope form is given as:

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

Therefore

$y-(-9) = - 9(x-2)$

$y+9 = - 9x +18$

This is the required equation of line in point slope form.

-1 3/4+ 1 1/6 what is the answer I say -7/12

Bingel [31]

Answer:

No, the correct answer of $-1\frac{3}{4} + 1\frac{1}{6}$ = $\frac{11}{12}$

Step-by-step explanation:

The given expression is $-1\frac{3}{4} + 1\frac{1}{6}$

As we know that a mixed fraction $a\frac{b}{c}$ can be converted into proper or improper fraction as $a\frac{b}{c} = \frac{ac + b}{c}$

⇒ $-1\frac{3}{4} = \frac{(-1) (4)+ 3}{c}$ = $\frac{-4 + 3}{4} = \frac{-1}{4}$

and, $1\frac{1}{6} = \frac{(1) (6)+ 1}{6}$ = $\frac{6 + 1}{6} = \frac{7}{6}$

Hence, the simplified expression = $\frac{-1}{4} + \frac{7}{6} = \frac{-1(3) + 7(2)}{12} = \frac{11}{12}$

or, $-1\frac{3}{4} + 1\frac{1}{6}$ = $\frac{11}{12}$

To find the answer.

The answer is sequence.

A "sequence" is an ordered list of numbers; the numbers in this ordered list are called "elements" or "terms". A "series" is the value you get when you add up all the terms of a sequence; this value is called the "sum".
