Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Slope-Intercept Form: y = mx + b

Step 1: Define
Point (-4, 47)
Point (2, -16)
Step 2: Find slope m
Substitute: [tex]m=\frac{-16-47}{2+4}[/tex]Subtract/Add: [tex]m=\frac{63}{6}[/tex]Simplify: [tex]m=\frac{21}{2}[/tex]Step 3: Find y-intercept b
Define: y = 21/2x + bSubstitute: -16 = 21/2(2) + bMultiply: -16 = 21 + bIsolate b: -37 = bRewrite: b = -37Step 4: Write linear equation
Combine all parts.
y = 21/2x - 37
y = 10.5x - 37

The sum of three numbers is 56. The second number is 2 times the third. The first number is 8 less than the third. What are the numbers?
Answer:
X = 8
Y = 32
Z = 16
Step-by-step explanation:
X + Y + Z = 56
Y = 2Z
X = Z – 8
Substitute the values from the second and third equation into the first equation:
Z – 8 + 2Z + Z = 56
Simplify
-8 + 4Z = 56
4Z = 64
Z = 16
So if Y = 2Z, Y = 2(16) = 32
And if X = Z – 8, X = 16-8 = 8

1. -25/4 DIVED -5 5/4
2. -3/21 x -3
Answer:
EZ PZ bruh
Step-by-step explanation:
First one, -25/4 ÷ -5 5/4
change the second mixed fraction into an improper one
=> -25/4 ÷ -25/4; dividing a number by itself gives you '1'
=> 1
second question,
=> -3/21 × -3; multiply the numerator with the other numerator, and since there is nothing given in the denominator of the second number mean its 1, hence multiply the denominator with the other denominator, and we get:
=> 9/21; we simplify this fraction and get: 3/7

Bert has three times as much money as Ernie. If Ernie spends $6 on a new rubber ducky, then Bert will have five times as much money as Ernie. How much money does Bert have?
Answer:
Bert has $45.
Step-by-step explanation:
I have no real strategy, except for that I used guess and check. How did I do this? Well, since I am in 5th Grade, I don't know algebra very well, so I made an organized chart and checked all the numbers that had to be a multiple and could be divided equally by 5, 3 and when a third of that number was subtracted by 6, it was a fifth of the orginal number. Thats how I got 45.
Checking this answer:
It is always important to check your answer after finishing the problem, so this is how I checked my answer:
1. 45 divided by 3 = 15
2. 15 - 6 = 9, and 9 is 1/5 of 45
Bert has $45.

How to solve a linear equation?A linear equation can be solved by equating the LHS and RHS of the equation following some basic rules such as by adding or subtracting the same numbers on both sides and similarly, doing division and multiplication with the same numbers.
The given equations are as below,
y = 2x + 6 (1)
y = 6x - 10 (2)
In order to find the variable x, equate equations (1) and (2) as follows,
2x + 6 = 6x - 10
⇒ 6x - 2x = 10 + 6
⇒ x = 4
Hence, the value of x is obtained as 4.
