y = 4 ( x + 2 ) y = 4 x + 8
The value of y will increase by 8.
so if you have x+2 then
y=4(x+2) distribute y=4x+8 y will go up by 8
Increasing the value of x by 2 in the equation y = 4 x results in an increase of 8 in the value of y . This is calculated by substituting the new value of x into the equation and finding the difference from the original y . Therefore, the effect is an increase of 8 in y .
