To solve a system of equations you can solve one equation for one variable and then use substitution to solve for the second variable.
A system of equations can have one solution, no solution, or infinitely many solutions. The solution is the point (or points) that would satisfy BOTH equations.
To graph a linear equation, you BEGIN with the y-intercept (b) and then MOVE using the slope (m). The point where two lines intersect is the solution to both linear equations.
The solution to a system of equations includes all x and y values that, when substituted into the equation, make the equation true.
A system of equations consists of two or more equations that use the same variables. When graphing, the solution will be the coordinates of the point of intersection of the two lines.
The solution to a linear equation consists of all the points that fall on the line or all x and y values that make the equation true.
Bivariate data can be represented and interpreted from two-way tables.
A line of best fit can be assigned to a scatter plot as a way of describing the trend and to help determine unknown outcomes.
Scatter plots are a way of representing data, and they can show positive, negative, or no correlation.
Numbers can be represented and related in various ways.
