The equation of the line which passes through points (2 3) and (-4 1) is 3y - x = 7.
What is the equation of the line?
The formula for a straight line is y=mx+c where c is the height at which the line intersects the y-axis, often known as the y-intercept, and m is the gradient.
Here, we have
Given: points (2 3) and (-4 1)
We have to find the equation of a line.
we need to determine the slope of the line. The slope can be found by using the formula
m = (y₂ - y₁) /(x₂ - x₁)
Now, we put the given points and get the value of m.
m = (1 - 3) /(-4 - 2)
m = 1/3
Now, we can use the point-slope formula to find an equation for the line. The point-slope formula states:
(y - y₁) = m(x - x₁)
(y - 3) = 1/3 (x-2)
3y - 9 = x - 2
3y - x = 7
Hence, the equation of the line which passes through points (2 3) and (-4 1) is 3y - x = 7.

Step-by-step explanation:

3x+9=36
Show your steps
Answer:
x=9
Step-by-step explanation:
3x+9=36
subtract 9 from both sides
3x=27
divide by 3 on both sides
x=9
The solution to the equation 3x + 9 = 36 is x = 9.
To solve the equation 3x + 9 = 36, we'll perform the necessary steps to isolate the variable x on one side of the equation.
Given equation:
3x + 9 = 36
First, we'll subtract 9 from both sides to eliminate the +9 term on the left side:
3x + 9 - 9 = 36 - 9
3x = 27
Next, to isolate the variable x, we divide both sides by 3:
(3x)/3 = 27/3
x = 9
Therefore, the solution to the equation 3x + 9 = 36 is x = 9.
In this equation, we start with an expression involving the variable x and a constant term. By performing algebraic operations, we manipulate the equation to have x on one side and the constant value on the other side. This isolates the variable and provides us with a specific value for x that satisfies the equation. In this case, the value of x is determined to be 9, which can be verified by substituting it back into the original equation to see if it holds true.

A 17 -ft ladder leans against a building so that the angle between the ground and the ladder is 79 .
Answer:
3.24 feet
Step-by-step explanation:
A 17 -ft ladder leans against a building so that the angle between the ground and the ladder is 79 . Find the distance between the building and the ladder
We solve the above question using the Trigonometric function of Cosine
cos x = Adjacent/Hypotenuse
Adjacent = x feet
Hypotenuse = 17 ft
The angle = 79°
Hence,
cos 79 = x/17
Cross Multiply
x = cos 79 × 17
x = 3.2437529214.feet
Approximately = 3.24 feet
Therefore, the distance between the ladder and the building = 3.24 feet
Posts are 4 1/4 feet in length. Posts must be installed 7/8 feet below ground level, What will be the height of fence?
Answer:
Step-by-step explanation:
4 1/4x7/8
I think 119/32
The height of fence will be "[tex]\frac{41}{8}[/tex]".
According to the question,
Length of posts,
= [tex]4\frac{1}{4} \ feet[/tex]
Length of posts below ground level,
= [tex]\frac{7}{8} \ feet[/tex]
Now,
→ The height of the fence will be:
= [tex]4\frac{1}{4} +\frac{7}{8}[/tex]
= [tex]\frac{17}{4}+\frac{7}{8}[/tex]
= [tex]\frac{34}{8}+\frac{7}{8}[/tex]
= [tex]\frac{34+7}{8}[/tex]
= [tex]\frac{41}{8}[/tex]
Thus the above is the right answer.
