Linear equations have four different types of slopes.
A zero slope is a horizontal line because all its
points have the same y-coordinate.
Linear equations have four different types of slopes.
A negative slope decreases from left to right.
Linear equations have four different types of slopes.
A positive slope increases from left to right.
What is a linear equation?
-
It 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 the linear equation true and plot those pairs on a coordinate grid, all of the points for any one equation lie on the same line. Linear equations graph as straight lines.
