Unlimited number of practice questions may be generated along with their detailed solutions. Solve each step below then click on "Show me" to check your answer. There is a graph at the bottom of the page that helps you further understand graphically the solution to the question.
Step by step solution
STEP 1: Let the point of intersection of the two lines have coordinates $(a,b)$. Write the system of equations whose solution, if any, is the ordered pair $(a,b)$.
STEP 2: Use Cramers rules to find the determinants $D$, $D_a$ and $D_b$ and solve the system of equations obtained in step (1).
STEP 3: Write the coordinates of the point of intersection.
Graphical Meaning of Solution
Below are shown the graphs of the two lines and the point of intersection if there is any. (Change scales if necessary)
