In the equation 2x+4=y, what is the value of y when x=5?

9514 1404 393

  y = 14

Step-by-step explanation:

Put the value of x where x is and do the arithmetic.

  2x + 4 = y

  2·5 + 4 = y . . . . . . substitute for x

  10 + 4 = y . . . . . . . multiply

  14 = y . . . . . . . . . . add

The value of y is 14 when x = 5.

To find the distance between these two points you will need to find the distance between the x values and the y values. from 4 to 1 on the y axis is 3 units, and from -3 to 6 on the x axis is 9 units. so, 3^2 + 9^2= c^2. this is 90=c^2. the square root of 90 is approximately 9.5 units.
