Use a graphing utility to solve the system of equations graphically. Round your solution(s) to two decimal places, if necessary.
$$\left\{\begin{aligned}
y &=e^{x} \\
x-y+1 &=0
\end{aligned}\right.$$

Key Concepts

System of Equations

A system of equations consists of two or more equations that share common variables. The solution to the system is the set of values for the variables that satisfy all the equations simultaneously. This concept is fundamental in algebra and helps in exploring how different equations interact with one another.

Graphical Methods

Graphical methods involve plotting each equation on a coordinate plane and finding the point(s) where the graphs intersect. This approach provides a visual representation of the solution to the system and is particularly useful when an exact algebraic solution is difficult or impossible to obtain.

Exponential Functions

Exponential functions are mathematical functions in which a constant base is raised to a variable exponent. They are characterized by rapid growth or decay depending on whether the exponent is positive or negative, and they commonly model processes such as population growth, radioactive decay, and interest calculations.

Linear Equations

Linear equations represent straight lines when graphed on a coordinate plane. They have a constant rate of change, defined by their slope, and a y-intercept that indicates where the line crosses the y-axis. Linear equations are widely used in various fields to model relationships with a constant rate of change.

Intersection Points

The intersection point of the graphs of two equations represents the solution to the system—where the two functions have the same value for the common variable(s). Finding the intersection point is a central aspect of solving systems of equations graphically.

Numerical Approximation and Rounding

Numerical approximation involves estimating the values of solutions when an exact answer is not easily obtainable. Rounding these approximations to a specified number of decimal places enhances clarity and precision in reporting the solution, especially when using digital tools or calculators.
