3.) 7x + 5y = -25

ax + by = r
Is called a linear equation in two variables.
The two variables are x and y.
The number a and b are called the coefficient of the equation
ax + by = r
The r is the Constant
That's why the x is always in the first and y is the second and r In the last. Because x is the highest degree and the y is the second, but r don't have degree.
