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)
