The equation of the line is written in the standard form, y = mx+c
It depends on what you are calling "standard form". 2x = 7 can be solved, but it is a standard form of an algebraic equation.
It is an expression in two variable: it is NOT an equation. There is no standard form for expressions.
x = 4.5
0.3y + 1.2 = 0.4 x Hence 0.4x - 0.3y - 1.2 = 0 or 0.4x - 0.3y = 1.2 To remove the decimal point multiply by '10' Hence 4x - 3y = 12 Make 'y' the subject 3y = 4x - 12 y = (4/3)x - 4
y + 4 = 2x −1
it is 1
Standard. You need a linear equation in two variables for slope-intercept form.
x + y = 3
In standard form it is 4x - 4y = 6 or 2x - 2y = 3
