In geometrey what are two different equations that describe the same line Such lines are called coincident lines?
What do you call equations describing two or more lines
How do you find the area of a figure using a grid?
You can't find the exact area of of most shapes with a grid, but you can get a pretty good approximation with the following method: 1) Count the number of squares completely inside the shape. Let's call this number X. 2) Count the number of squares that are partially inside the shape (squares with the shape's outline passing through them). We'll call this number Y. 3) A = X + 0.5Y The answer is in squares, so you need to know the grid spacing if you want to convert to inches or something. Remember, this isn't exact. The smaller the squares, the better the results. If you need to be really accurate, try the following: 4) Repeat steps 1 - 3 for a bunch of different grid sizes (e.g. 1", 0.5", 0.25". 0.125", etc.). 5) Graph the results from step 4 as Area vs. Grid Size. 6) Draw an approximate curve through the points you graphed, and estimate the asymptote as Grid Size approaches infinity. Carefully cut out the figure and mass it on a good balance. Cut out a square or rectangle of about the same size as the figure from the same grid paper and carefully mass it on the balance. You can then calculate the mass per grid square or mass per unit area. Divide the mass of the figure by mass per unit area and you have the area.
What equations represents a line parallel to the line given by y equals 5x plus 9?
The equations will have the same slope as y = 5x+9 but a different y intercept
If the graphs of two linear equations in a system have the same slope the system has what kind of solution?
If they have the same slope, then there are two possibilities. First say they have the same slope and different y intercepts. This means they are parallel lines and there is no intersection. The solution is the empty set or we say there is no solution.If the y intercept is the same, then the two equations represent the same line. In this case there is an infinite number of solutions.
When a figure is translated on a coordinate grid what conclusion can you draw from the pre image and image?
That the image has moved in the same direction and distance of its outline
