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
What does it mean if there are an infinite number of solutions for a system of linear equations?
It means that the equations are actually both the same one. When they're graphed, they both turn out to be the same line.
A definition of a solution to a system of equations?
A system of equations is a set of two or more equations with the same variables, graphed in the same coordinate plane
What are lines that have equivalent linear equations and overlap at every point when graphed?
coincidental -Lines that share the same solution sets.
What is the solution of the system 2x plus 3y equals 2 and 4x plus 6y equals 4?
That system of equations has no solution. When the two equations are graphed, they turn out to be the same straight line, so there's no such thing as a single point where the two lines intersect. There are an infinite number of points that satisfy both equations.
What is the equation of a line with a y- intercept at 8 that has the same slope as the segment shown on the grid?
Not enough information has been given but in general straight line equations are parallel if they have the same slope but different y intercepts.
What is equivalent ratio's equation?
Equations are said to be equivalent if they have the same solution. This definition also holds true in rational equations or equations involving rational expressions. For instance, the equations 2x = 14 and x - 3 = 4 are equivalent. Why? It's because they have the same solution, that is x = 7.
What are equations that have the same answer?
Simultaneous equations have the same solutions
Is the slope and intercept the same thing in math?
No. You are referring to a line on an XY graph, where X is the horizontal axis and Y is the vertical one. Equations are commonly graphed this way. Slope refers to the angle at which the graphed line goes up or down. If it is steep, it is a higher slope. If it is closer to flat, it is a low slope. Intercept refers to the point at which the line crosses the Y axis.
What are lines that overlap at every point when they are graphed?
They are the same line.
What is equations that have the same solutions?
Simultaneous equations have the same solutions.
What is equivalent equation?
Two equations are said to be equivalent if and only if they have the same solutions.y = (x - 3)2 + 5
What are equivalant equations?
Equivalent equations are equations that have the same solution set.
