Y 2x 1. The slope is how fast the line moves up or down. That is it concerns two-dimensional sample points with one independent variable and one dependent variable conventionally the x and y coordinates in a Cartesian coordinate system and finds a linear function a non-vertical straight line that as accurately as possible predicts the.
So 1 is also needed.
In a linear equation both terms have to be constant. When x increases y increases twice as fast so we need 2x. Y 2x 1. A linear equation is defined as an equation where the greater power of the unknown is one.
