Here the highest power of each equation is one. In particular the three main forms of linear equations are slope-intercept point-slope and standard form. Consider the equation 7x 35 0.
Y ax b.
The equation for a straight line is a linear equation. For example 4x 5 0 is a linear equation of one variable. Examples No1 x 6 8 is a linear equation. A and b are called constants.
