Answer to Problem 57PPE
Slope intersection and graphical.
Explanation of Solution
Given:
Equation is linear
One way to determine whether an equation is linear is by graphing the line.
Another way to determine is by rewriting in slope-intercept form
Example:
Consider an equation,
Now, draw the graph of above equation using graphing calculator.
Graph:
