for something to be an equation it has to be equal to something.2x+3=0 would be a linear equation (with x=-1.5) 2x+3+0 is just a series of terms.
A linear equation.
The y-intercept of a linear equation is the point on the y-axis at which the line cuts.It could be found by plugging x = 0 in the given linear equation.For example,Consider 3x + 2y = 6. To find the y-intercept just plug x = 0 in the equation.3(0) + 2y = 62y = 6y = 3(0, 3) is the y-intercept of the linear equation 2x + 3y = 6.Note:In the same way we can find the x-intercept by plugging y = 0 in the given linear equation.
No a linear equation are not the same as a linear function. The linear function is written as Ax+By=C. The linear equation is f{x}=m+b.
An equation is linear if and only if all of the unknown quantities are multiplied by a constant and added to the rest of the left or right side. In other words, there are no powers, trig, etc. ex. 5x -y = 12 is linear. 3a +4b +5c +19d +pi*f = 0 is linear. sin(x) = 0 is not. x^2 = y-15 is not.
