A train travels in a straight path at a steady speed of 1.25 miles per minute. at noon, the train is 100 miles from the starting
point. express the distance d from the starting point as a function of time, x, in minutes after noon. d = 100 2.5 x d = 1.25 x d = 1.25 100 x d = 100 1.25 x
A linear equation only has one or two variables. No variable in a linear equation is raised to a power greater than 1 or used as the denominator of a fraction. When you find pairs of values that make a linear equation true and plot those pairs on a coordinate grid, all of the points lie on the same line.
An example of linear equation is y=mx + b. A polynomial equation of the first degree (such as x = 2y - 7)
A linear equation is an algebraic equation where each term has an exponent of 1 and when this equation is graphed, it always results in a straight line. This is the reason why it is named as a 'linear equation'.
