1. If the slope (m) is then the line rises to the right. 2. It is a two dimensional system consists of two number lines drawn perpendicular to each other on a plane. 1 3. The point of intersection of the two coordinate axes is called the 4. 5. is defined as a ratio of the vertical line to its corresponding run. is an equation that can be written in the form ax + by = c, where a, b and c are real number, but a and b cannot both be zero. 6. In a rectangular coordinate system, the x-coordinate is called the 7. The graph of a linear equation in two variables is a 8. In the Cartesian Coordinate System, the vertical line is known as the 9. If the slope (m) is then the line falls to the right. 10. The slope of any non vertical straight line containing the points with coordinates ( X₁, Y₁ ) and (X₂, Y2 ) is defined by the formula​
