Need help fast.. I WILL MARK U BRANLEYS IF U ANSWER CORRECTLY
Oxana [17]

Step-by-step explanation:

The line

y =  -3x + 3

Is in point Slope form. This means the Slope and the y intercept are visible in the equation 9f the form

y = mx + b

Where m is the Slope of the line and b is the y coordinate of the y intercept.

To determine the y intercept, assume x = 0, then - 3x = 0, so y = 3 and x = 0 (0,3}

From that point you can find the next point by choosing a value for x in the given equation to find a corresponding y.

Substitute 1 for x and get 0 for y, (1,0)

Substitue 2 for x and get - 3 for y, (2,-3)

To answer the questions use the supplied coordinates in the original equation.

#1. (-1,6)

6 =  - 3( - 1) + 3

6 = 3 + 3

This is a true statement, so the line does pass through this point.

#2 (12,-33)

- 33 =  - 3(12) + 3

- 33 =  - 36 + 3

Again, the statement is true, so the line passes through the point.

#3 (2,9)

9 =  - 3(2) + 3

9 =  - 6 + 3

This is a false {untrue} statement, so the point does not sit on the line.

A little help would be nice here pls
MArishka [77]

Answer:

11). 3x² -x    12). -5x + 5

Step-by-step explanation:

11). (4x² + x) - (x² + 2x)

4x² + x - x² - 2x

4x² - x² + x - 2x

3x² -x

12). (6x - 3) - (11x -8)

= 6x - 3 - 11x + 8

= 6x - 11x - 3 + 8

= -5x + 5

"Find the midpoint of AB .
Diano4ka-milaya [45]

Answer:

The midpoint of AB = (x,y)=(1,1)

Step-by-step explanation:

Given : A line AB

To find : Midpoint of AB.

Solution :

Consider the figure


Then , Points of A =    (x_{1} ,y_{1} )   = (-2,0)


Points of B =    (x_{2} ,y_{2} )   = (4,2)


Now to find mid point we will use midpoint formula :


(x,y) =(\frac{x_{1} +x_{2} }{2},\frac{y_{1} +y_{2} }{2} )


(x,y) =(\frac{-2 +4 }{2},\frac{0 +2 }{2} )


(x,y) =(\frac{2 }{2},\frac{2 }{2} )


(x,y) =(1,1 )


Thus, The midpoint of AB = (x,y)=(1,1)

Which function is increasing and has a constant slope?
ratelena [41]

We need to find the increasing function with constant slope.

Let us check each option one by one.

A) 6x -5y =10.

Let us solve it for y to get slope-intercept form

6x-5y =10.

-5y =-6x +10.

y =6/5 x-2.

<em>Slope is 6/5 positive, therefore, it's an increasing function.</em>

<em>A linear function always has a constant slope.</em>

<h3>Therefore, correct option is option A.</h3><h3>A. 6x -5y =10</h3>

All other options are incorrect.
