Question

Hi can anyone that understands this please answer it for me?

I was trying to work ahead with my tutor last week and then I stopped doing the assignment and forgot how to do it, it’s also the end of my quarter in 3 days and I have to redo a LA essay.
Thank you!

Answer 1

Answer & Step-by-step explanation:

We can make y the subject first

y =
`(1)/(5)`(x + 8) - 7

Substitute values of x into the equation to find their corresponding y value

For example, when x is 0

`(1)/(5)`(0 + 6) - 7 = -5.8

When x is 1, y = -5.6

Repeat for other values of x

Here is an example of me plotting the points for x from -2 to 2:

Answer 2

see attachment.

Explanation:

To find:-

• The graph of the line.

Answer:-

We need to find out the graph of the following line,

`:\sf\implies y + 7 = (1)/(5)(x+6)\\`

For graphing this line we need to find at least two coordinates through which the graph passes . We can find out the third point to check if the other coordinates are correct.If all the three points do not come in a straight line , then there is some mistake .

Now solve out for any of the variables , i am solving out for "y" .

For that subtract 7 on both the sides,

`:\sf\implies y =(1)/(5)(x+6)-7 \\`

Substitute x = 4 :-

`:\sf\implies y =(1)/(5)(4+6)-7 \\`

`:\sf\implies y = (10)/(5)-7 = 2-7 \\`

`:\sf\implies \pink{ y =-5} \\`

Therefore one of the coordinate to mark on the graph is (4,-5) .

Again, substitute x = -6 ,

`:\sf\implies y =(1)/(5)(-6+6)-7\\`

`:\sf\implies y = 0 - 7 \\`

`:\sf\implies \pink{ y = -7} \\`

Therefore the second coordinate to mark on the graph is (-6,-7) .

After marking these two points join the points by drawing a line. The line will represent the graph of the given equation.
