In a coordinate point, the values would go (x,y). Substitute the x and y values from the coordinate points into the equation given.
8(3)+B(4)=40

Multiply 8x3
24+B(4)=40

Subtract 24 from both sides

4B=16

Divide the whole equation by 4

B=4

Write the standard form of the line that passes through (-1,-3) and (2,1)
Pie
Answer:

5 =  - 2x - y
To find this you must find the slope first:
\frac{y - y1}{x - x1}
which is, after performing some calculating is -2.

Next you need to set up your eqaution:
y - y1 = m(x - x1)
when you set it up, and substitute the variables for your slope and points you should get this:
y - ( - 3) =  - 2(x - 1)
y + 3 =  - 2x - 2
add 2 to both sides
y + 5 =  - 2x
subtract y from both sides
5 =  - 2x - y

Solve for X.<br> 4(2x + 5) + 2x + 3 = -11
S_A_V [24]
We can begin by rewriting the problem:

4(2x + 5) + 2x + 3 = -11

Let’s solve in steps.

1. Distribute

8x + 20 + 2x + 3 = -11

2. Combine like terms

10x + 23 = -11

3. Subtract 23 from both sides

10x + (23 - 23) = -11 - 23

10x = -34

4. Divide both sides by 10

10 / 10 = 1 (or x)

-34 / 10 = -3.4

Therefore, x = -3.4.
