For finding the coordinate plane   for the given equation y = 3x +5 Where value of x =4 we need to follow the steps given below:
Step 1: Given equation is
y =3x +5,
As we know, value of x so we put value of x in the equation and find value of y
y = 3x 4 +5 = 17 (here we have given x =4)
y =17 After solving we get value of y
Step 2: Now, find the Coordinate Plane for given equation:
By above step we get x =4 and y = 17,
It means coordinate plane is (x, y) = (4, 17).
