Question

Enter one number into each box to complete the table

Answer 1

For the missing x value in the table, replace y by -2.5 in the equation and solve for x:

y= 1/2x - 5

-2.5 = 1/2x-5

-2.5+5 = 1/2x

2.5 = 1/2x

2.5/ (1/2) = x

x= 5

For the missing y values replace by the corresponding x values and solve:

x= 7

y= 1/2(7)-5

y= 3.5-5 = -1.5

x=10

y= 1/2 (10) -5

y= 5-5

y=0
