That's because division by zero is undefined. When calculating slopes, the ratio is one number divided by another number.īy definition a ratio cannot have a denominator of zero. Slope is defined as the ratio of the change in the y-coordinates over the change in the x-coordinates. Your browser does not support the video tag. Watch this video to learn about undefined slope. The slope of the line that crosses these two points has a slope of 1. That means that 7 minus 3 in the numerator and 6 - 2 in the denominator. Take those coordinates and plug them into the slope formula. For the purposes of the slope formula, let's call these coordinates x1 and y1, and let's call these coordinates x2 and y 2. To find the slope of the line that crosses these two points, use the slope formula. This point has coordinates 2, 3 and this point has coordinates 6,7. Use those coordinates in the slope formula to calculate the slope. This one has coordinates x1 and y1 and this one has coordinates x2 and y2. When you know the coordinates of two points, use this version of the slope formula. In terms of the coordinates, it is the ratio in the difference in the y coordinates over the difference in the x coordinates. It is the ratio of the Rise over the Run, or the ratio of this vertical distance over this horizontal distance. Use it when you want to find the slope of the line that connects two points. According to them, these math apps can aid the teachers and students in solving linear equations, inequations, etc.This is the slope formula. In Patterns and Algebra, the master teachers instructed the seasoned teachers to venture on using my script calculator, lecture notes, and photomath. These are web-based graphing calculators that include basic construction in Geometry. The master teacher participants advised the seasoned teachers to use platforms such as Desmos and Khan Academy to address their challenges. In addition, the teachers mentioned that they find difficulty integrating technologies on topics in Algebra especially word problems. As to Patterns and Algebra, all 21 teacher participants mentioned that the topics that hard to be applied with modern technologies were irrational numbers, solving problems in linear equations, operation on polynomials and inequalities, and fundamental operations on algebraic expressions. They added that it’s hard for them to use modern technologies on sets because of the excessive board work. They said that set and union set are their difficulties since they find complications in looking for figures, and illustrations that needed to present in the class. The teacher participants mentioned that they found difficulty in making power-point presentations in basic constructions in Geometry. The interview was done during the one-week seminar training in the application of different math applications to the classroom setting. Basic qualitative research was used in this study.
