Answer:

<h3>y=-x+9</h3>

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(9-0)/((0-9))

m=9/(0-9)

m=9/-9

m=-1

y=mx+c

y=-1*x+c

y=-x+c

plug in (9,0) into the equation

0=-1*9+c

0=-9+c

-c=-9

c=9

y=-x+9

you wrote it correctly too, but I think the problem is that it only takes -x not -1x

Answer:

y = - x +9

Step-by-step explanation:

slope = (9-0)/(0-9) = - 1

line equation : y= mx + c

find c : 9= - 1*0 +c ....... >> c = 9

y = - x +9 ans

A. <br> -3y − 2x = 5<br> B. <br> 3y − 2x = 5<br> C. <br> 3y − 2x = -5<br> D. <br> 3y + 2x = 5
Airida [17]

Answer:

C) 3y -2x= -5

Step-by-step explanation:

(1,1), (4,3)

slope= y2-y1/ x2-x1

slope= 3-1/4-1= 2/3

(4,1)

Substitute into y=mx+b

1= 4(2/3)+b

1= (8/3) +b

-5/3= b

3(y= 2/3x -5/3)

3y= 2x -5

3y -2x= -5

The roots of a quadratic function are x = -3 and x = 2/3. Which of the following would be the constant term of the equation in s
Alla [95]

Answer:

-2

Step-by-step explanation:

Since the roots are known and the function is a quadratic function, we can write down the function:

y = (x+3)(x-2/3) since when the roots are plugged in, the function gives 0.

Standard form means that the function has to be expanded:

y = (x+3)(x-2/3) = x^{2}+3x - 2x/3 - 3*2/3

y = x^{2}+ 7x/3 - 2

The constant term is -2.
