Isla wants to solve the equation 2.5x – 1.75 = 5(7 – 0.5x). She uses a graphing program to graph the equations y = 2.5x – 1.75 and y = 5(7 – 0.5x). Use the graph to find the solution of 2.5x – 1.75 = 5(7 – 0.5x). Math item stem image

horizontal translation of 2 units in the positive x direction

followed by

vertical translation of 3 units in the positive y direction

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
