Equation 2 gives the graph of a line with a \(y\)-intercept of 0 and a slope of 1. If we plot both lines on the same graph, they look like this: The solution to the system of equations is represented on the graph by the point where the two lines intersect. By looking at the graph of these two lines, we can see that they cross at the point \((1 ...

# Equations and graphs lesson 9.5 answer key

In general, a system of linear equations can have: No solutions. In this case, the lines that correspond to each equation never intersect. Exactly one solution. The lines that correspond to each equation intersect in exactly one point. An infinite number of solutions. The graphs of the two equations are the same line! Lesson 13 Practice Problems Solving Equations What is an Equation? An equation says that two things are equal. It will have an equals sign "=" like this: When you have the equation of a straight line, you can always do quick and easy graphing by starting with the y-intercept value, and then plotting other points by using the slope value. In "real life", this may not work so well. For instance, I probably wouldn't try eye-balling the plot points for an equation like, say, y = 0.0062x – 379.04 ...

When working with equations that have two variables, the coordinate plane is an important tool. It's a way to draw pictures of equations that makes them easier to understand. To create a coordinate plane, start with a sheet of graph or grid paper. Next, draw a horizontal line. Lesson 5.6 – Writing Equations, Graphing Circles CC Geometry Do Now 1. Determine the center, radius, and diameter of the following circles. a) b) 2. The equation for part (a) on the Do Now has a circle equation of (x + 3) 2 + (y – 3) = 9 and the equation for
