Write the slope-intercept form of the equation of each line.

gregori [183]

Greetings!

Answer:

2y = x - 6

Step-by-step explanation:

First, we must find the slope of the current equation.

This is the number in front of the x.

Seeing as this is -2x, the slope of this line is -2

When finding the slope of a line perpendicular, you need to find the $\frac{-1}{slope}$

So, in this case it is:

$\frac{-1}{-2}$

The negatives cancel out which leave $\frac{1}{2}$

So the gradient is $\frac{1}{2}$

Now, to find the equation of a line, you need to use:

y - y1 = m(x - x1)

Where ya and x1 are the values in the coordinates (2 , -2)

So y1 = -2, x1 = 2, and m is a half. Plug these values in:

y - - 2 = $\frac{1}{2}(x - 2)$

We need to get rid of the half so we multiply the whole equation by 2:

2y - - 4 = (x - 2)

The minus and the negative turn into a positive:

2y + 4 = x - 2

And now simply move the +4 over to the other side, making it a negative:

2y = -2 - 4 + x

Simplify:

2y = x - 6

<h3>So the equation of the line is 2y = x - 6</h3>

The graph shows how many apples Erin can pick if she maintains a constant rate. What is the linear equation for this relationshi

Ainat [17]

Answer:

The linear equation $y=50(x)$ and Erin can pick $50$ apples per hour if she maintains a constant rate.

Step-by-step explanation:

To find the linear equation of the relationship from the graph.

We have to find the coordinates .

Let say $(x,y)=(1,50)$ and $(x_1,y_1)=(2,100)$

Here $x$ variable is the time in hour and $y$ variable is the number of apples.

To find linear equation we have to find the slope (m) of the line by using point-slope form.

$m=\frac{y_1-y}{x_1-x}$

So,

$m=\frac{100-50}{2-1}=50$

The the linear equation will be.

$y=50(x)$

Number of apples Eric pick in an hour is $50$ .

By plugging the value of $x=1$ in the equation we can find the number of apples picked by Erin per hours subsequently $x=2$ for second hour.

In each hour she picks $50$ apples.

Linear equation is $y=50(x)$ and number of apples picked by Eric in an hour is $50$ .

Find the first fourth and eighth terms of A(n)=-2•5^n-1

Mila [183]

The first term is 0. The fourth is 1000. The eighth term is 10,000,000. All you have to do is plug the term you want to find into n and then solve.

Please help!!

miss Akunina [59]

Answer:

Solution of the system of equations will be (6, 6).

Step-by-step explanation:

Table for the first equation,

$y=\frac{1}{2}x+3$

x 0 2 4 6 8

y 3 4 5 6 7

(x, y) (0, 3) (2, 4) (4, 5) (6, 6) (8, 7)

We have got the values of y by substituting the values of x in the given equation for the table.

Similarly, for the other equation,

y = 2x - 6

x 0 2 4 6 8

y -6 -2 2 6 10

(x, y) (0, -6) (2, -2) (4, 2) (6, 6) (8, 10)

By analyzing both the tables we find (6, 6) is a common point in both the tables.

That represents the points of intersection of both the lines.

Therefore, solution of the system of equations will be (6, 6)
