For the equation 6x – 3y + 2z = 12, the value of the y-intercept is -4

Solution:

Given, equation is 6x – 3y + 2z = 12

We have to find the value of y – intercept for the above equation.

Now, we know that, value of y – intercept is the value of y at a point where the line equation meets the y – axis in the co – ordinate plane.

We also know that, when a line meets y – axis, the values of remaining variables becomes 0.

Then, put 0 in place of x and z in equation ⇒ 6( 0 ) – 3y + 2( 0 ) = 12  

⇒ 0 – 3y + 0 = 12  

⇒ -3y = 12  

⇒ y = -4  

Hence, the value of y – intercept is – 4
