Point x and point z are shown on the number line where point x represents 2/3. The sum of a number y and point x is represented by point z. Which rational number is one possible value of y? Explain.

Ican’t i can’t do it

To find the x-intercept, make  y  equal to zero, and solve for  x. to find the y-intercept, make  x  equal to zero, and solve for  y.explanation: y=4x−2x-intercept0=4x−2add  2  to both sides of the equation.2=4xdivide both sides by  4.24=xsimplify.12=xswitch sides.x=12y-intercepty=4(0)−2y=−2
