8. True or false: in order to solve the following equation, you would first subtract by 4, then multiply by 5/1 *
4+1/5=-1
To solve 3x + 2 = 23 you must:
Subtract 2 from both sides so like this 3x+2−2=23−2 and get 3x=21.
Now Divide both sides by 3 so 3x/3=21/3. Mainly divide 21/3 and get 7.
--------------------------------------------------------------------------------
To solve -2y - 7 = 3 you must:
Add 7 to both sides so like this −2y−7+7=3+7 and get −2y=10.
Now Divide both sides by -2 so -2y/-2=10/-2. Mainly divide 10/-2 and get 5.

Part 2) The graph in the attached figure
Step-by-step explanation:
Part 1)
we know that
The linear equation in slope intercept form is equal to
where
m is the slope
b is the y-intercept
we have
substitute in the linear equation
solve for b
substitute
Part 2) Draw the equation
we know that
To graph a line we need two points
we have the y-intercept (0,4) and (2,-4)
Plot the points, connect them and join to draw the line
see the attached figure

The expression which describe the situation is,
⇒ (1 - 1/3) × 1/6
What is an expression?
Expression in math is defined as the collection of the numbers, variables and functions by using signs like addition, subtraction, multiplication, and division
Given that;
When you make a large bowl of salad with your friends. Your brother eats 1/3 of it.
Now,
Let total amount of salad = 1
Amount of salad after brother eating = 1 - 1/3 = 2/3
And, Amount of salad for diving into 6 friends = 2/3 × 1/6
= 1/9
So, Each friend get 1/9 of a salad.
Thus, The expression which describe the situation is,
⇒ (1 - 1/3) × 1/6
