Answer:

y = x+7

Step-by-step explanation:

Assuming all of these numbers are ordered pairs (coordinates)  when x is 1 y is 8, when x is 2 y is 9 and so on.  If you notice y is going up by 1 every time so it follows that the starting point (y intercept) must be 7.  Therefore, our equation will be y = x + 7.  

Test it out:

Let x =2

y = 2 + 7 = 9  This matches our coordinate (2,9) so it's correct.

Let x =4

y = 4 + 7 = 11  This matches our coordinate (4,11) so it's correct.

Feel free to try out the rest of the coordinates, but usually 2 is enough to confirm that your equation is correct.

PLEASE HELP ME!!!! Nancie and Suresh are typing. The rate at which Nancie is typing is represented by the equation y = 35x, wher

<span>answer 1
 Nancie is typing is represented by the equation
 y = 35x
 Therefore, the rate at which Nancie is typing is given by the slope of the straight line that in this case is:
 35 words per minute
 answer 2
 To find the rate at which Suresh is typing we have to find the equation of the line with the data in the table.
 For this case, the equation of the line will be given by:
 y = 56x
 Therefore, the rate at which Suresh is typing is given by the slope of the straight line which in this case is:
 56 words per minute
 answer 3
 Nancie's rate = 35
 Suresh's rate = 56
 56-35 = 21 words per minute
 Nancie's rate is 21words per minute less than Suresh's rate.

What is the property that justifies the illustrated step in solving the equation?
andrew11 [14]
Commutative property of addition is being used.

This means that you can switch around where the numbers are and still get the same answer.

Hope this helps!
