Answer:

The "2" in the second term is a coefficient.

Step-by-step explanation:

$3x^2-11(2y+1)+4$

In the given expression ,

3 in the first term is a the coefficient of x^2

11 is the factor of second term

4 is the constant in third term

2 is the coefficient of y

So, The "2" in the second term is a coefficient.

line passes through the point (0, –1) and has a positive slope. Which of these points could that line pass through? Check all th

sammy [17]

Answer:

Points passing though are (12, 3),(–2, –5) and (1, 15)

Step-by-step explanation:

For a line passing through (x₁,y₁) and (x₂,y₂) slope is given by $\frac{y_2-y_1}{x_2-x_1}$ .

Here we have one point (0, –1), we need to check slope of all the points given.

(12, 3)

$m=\frac{3-(-1))}{12-0}=\frac{1}{4}>0$

(–2, –5)

$m=\frac{-5-(-1))}{-2-0}=\frac{-4}{-2}=2>0$

(–3, 1)

$m=\frac{1-(-1))}{-3-0}=\frac{2}{-3}=-\frac{2}{3}$

(1, 15)

$m=\frac{15-(-1))}{1-0}=\frac{16}{1}=16>0$

(5, –2)

$m=\frac{-2-(-1))}{5-0}=\frac{-1}{5}=-\frac{1}{5}$

Points with positive slope are (12, 3),(–2, –5) and (1, 15)

Solve each system by graphing y=-x+5 and y=2x-4

makkiz [27]

In order to graph y=-x+5, make a table and plug in values of x to find y. to find your points, use x,y.
x: 1 y: 4
x: 2 y: 3
x:3 y: 2
x: 2 y:1
these are the first four points for the first equation. to plug in, use ramdom numbers for x, such as 1, 2, and 3. y= -(1) +5

Find the slope 9,4 and 0,5

son4ous [18]

$\bf \begin{array}{ccccccccc}
&&x_1&&y_1&&x_2&&y_2\\
% (a,b)
&&(~{{ 9}} &,&{{ 4}}~) 
% (c,d)
&&(~{{ 0}} &,&{{ 5}}~)
\end{array}
\\\\\\
% slope = m
slope = {{ m}}\implies 
\cfrac{\stackrel{rise}{{{ y_2}}-{{ y_1}}}}{\stackrel{run}{{{ x_2}}-{{ x_1}}}}\implies \cfrac{5-4}{0-9}\implies \cfrac{1}{-9}\implies -\cfrac{1}{9}$
