y=5.5
The simplification of the expression 3(2x + y is 6x +3y
According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.
For example, a ( x +y) can be written in the form
ax + ay .
Similarly, simplifying 3(2x +y) using distributiveproperty means
3× 2x + 3 × y
= 6x + 3y
Therefore the simplification of the expression 3(2x + y) is 6x + 3y.

Answer:
4
Step-by-step explanation:
Let us first solve for the slope (m) of the perpendicular line.
The slope of the perpendicular line is -5/3.
Thus, for the slope of the line, we get,
Let us solve for the value of b with the given value of slope (m) = 3/5 and (x,y) = (-5,1).
Let's now make the equation of the line using Slope-Intercept Form,
Given, m = 3/5 and b = 2
What is the equation of the line in point-slope form?

= {(x + 4)
Oy+4=;
O y-4 = 2(x + 4)
N
Oy - 0 = 2(x-4)
Oy - 4 = 2(x -0)

-2.
2.
the equation of the line in slope-intercept form is:
y = (1/2)x - 2
A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.
From the graph, two points on the line are (-4, -4) and (4,0),
The formula for the slope of a line is:
m = (y₂ - y₁) / (x₁ - x₁)
where (x₁, y₁) and (x₂, y₂) are two points on the line.
Using the given points (-4, -4) and (4, 0), we can calculate the slope:
m = (0 - (-4)) / (4 - (-4))
m = 4 / 8
m = 1/2
Now that we know the slope, we can use the slope-intercept form of a line, which is:
y = mx + b
where m is the slope and b is the y-intercept.
To find the y-intercept, we can use one of the givenpoints on the line. Let's use the point (-4, -4):
y = mx + b
-4 = (1/2)(-4) + b
-4 = -2 + b
b = -2
Therefore, the slope-intercept form of the line is y = (1/2)x - 2.

Answer:
A
Step-by-step explanation:
For point-slope form, you need a point and the slope.
y - y₁ = m(x - x₁)
Looking at the graph, the points you have are (4, 0) and (-4, -4). You can use these points to find the slope. Divide the difference of the y's by the difference of the x's/
-4 - 0 = -4
-4 - 4 = -8
-4/-8 = 1/2
The slope is 1/2. This cancels out choices C and D.
With the point (-4, -4), A is the answer.
