We know the y intercept is 16 because y=16 when x=0.

Find slope by calculating change in y over change in x.
(12-16)/(2-0)
-4/2
-2

Plug both values into slope intercept form. y=mx+b where m is slope and b is the y intercept.

Final answer: y=-2x+16

Find the point, M, that divides segment AB into a ratio of 3.1 if A is at (-4,-2) and B is at (4. -10).

Natasha_Volkova [10]

Answer:

The coordinates of M are (2,-8)

Step-by-step explanation:

The coordinates of the point that divides the line segment joining

$A(x_1,y_1)$ to $B(x_2,y_2)$ in the ratio m:n is given by:

$(\frac{mx_2+nx_1}{m+n},\frac{my_2+ny_1}{m+n})$

If A is at (-4,-2) and B is at (4. -10) and the ratio is 3:1.

Then

$(\frac{3(4)+1(-4)}{3+1},\frac{3(-10)+1(-2)}{3+1})$

$(\frac{8}{4},\frac{-32}{4})$

The coordinates of M are (2,-8)

Answer:

Step-by-step explanation:

y = 3x + 2

6x – 2y = 10

Ryan’s answer:

I solved by adding the equations. The solution is .

y = 3x + 2 → 3x + y = 2

6x – 2y = 10 → 3x – y = 5

6x = 7

x =

6x – 2y = 10 → 6 – 2y = 10

7 – 2y = 10

–2y = –3

y = -

Jesse’s answer:

I used matrices. The solution is .

Mark’s answer:

I graphed the equations. The lines are parallel and do not intersect, so there is no solution.

4. Which operation should be completed first in the expression below? Use PEMDAS to evaluate. 24 ÷ (12 – 8) x 6 + 3 a. Add b. Su

irinina [24]

Answer:

Option b - Subtract

Step-by-step explanation:

Given : Expression $24\div(12-8)\times 6+3$

To find : Which operation should be completed first in the expression below?

Solution :

P - Parentheses

E - Exponent

D - Divide

M - Multiplication

A - Addition

S - Subtraction

In the first step we solve the bracket in the expression $24\div(12-8)\times 6+3$

So, we do subtraction i.e. 12-8=4

Therefore, option b is correct.
