Use the rule y = -x + 7 to fill in the blank. if (1, y) is on the graph, then y = explain

The answer is:  " 6 " .

    →   "  y  =  6 " .

Step-by-step explanation:

We are given the equation:

  y  =  - x  +  7  ;

We are given that:  " ( 1 , y ) "  ;  

            is a point on the graph.

So, we are asked to find the value for " y " in the given

equation when " x = 1 " .

So, given the equation:

   y  =  - x  +  7  ;

Substitute:  " 1 " for " x" ;  and:  "Solve for "y" :

   y  =  - (1) + 7  ;

  y   =  -1  +  7  ;

  y   =  7  + (-1) ;

  y   =  7  -  1   ;

  y   =  6 .

The answer is:  " 6 " .

    →   "  y  =  6 " .

Hope this answer — and explanation — was of help!

Best wishes!

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.
