Answer it pls and explain too​
snow_tiger [21]

Answer:

  y-intercept: (0, 5); slope: 1/4

Step-by-step explanation:

The slope (m) is found from ...

  m = (y2 -y1)/(x2 -x1)

Using the first two points in the table, this is ...

  m = (8 -6)/(12 -4) = 2/8 = 1/4 . . . . . eliminates choices A and C

__

Then, the point-slope form of the equation of the line can be written as ...

  y -y1 = m(x -x1)

  y -6 = (1/4)(x -4) . . . fill in known values

  y = 1/4x -1 +6 . . . . . add 6

  y = 1/4x +5

Then the value of y when x=0 is ...

  y = 0 +5 = 5

So, the y-intercept is (0, 5) and the slope is 1/4, matching the last choice.

Which expression represents this word phrase?<br><br> five more than the product of x and 6
disa [49]

<u><em>Answer:</em></u>

<u>The expression is:</u> 6x + 5

<u><em>Explanation:</em></u>

Product means <u>multiplication</u>

Therefore, the product of x and 6 means that we will multiply x by 6

<u>This would give us:</u> 6x

Now, five more than the product means that we will <u>add</u> 5 to the product we just obtained

<u>This means that:</u>

<u>five more than the product of x and 6 is:</u>

6x + 5

Hope this helps :)

madam [21]
Astronomers deal with objects in space, so it's most likely they would use geometry to determine how far they are, how big they are, etc.
