Since my answer was deleted here it is:
The variable x represents the cost per pound of meat.
The variable y represents the cost per pound of cheese.
The deli charges $4.50 for a pound of meat.
Have a great day! (this is late but for anyone else who needs it)
The slope is the coefficient of x, which is 10, and the y-intercept is the constant, which is 5.
First of all, the identity property of multiplication (which is what this is I'm assuming) is that the number 1 multiplied by any other number is that number itself. (An example would be 2 multiplied by 1, which would be two) So in this problem, this rule applies too, since 2/3 multiplied by 1 would be 2/3!
Hope this helped :)
If x=-5 (-5)2+2=27
likewise put -4 -3 -2 -1 0 1 2 3
and in another equation also.
I've included two pictures showing steps on how to solve. Hopefully this helps more than words.
