Find the equation of each of the lines graphed below. Then confirm algebraically that (1, 1) is the point of intersection. Homework Help ✎
Use y = mx + b.
You need to find the slope and y-intercept of each line.
For one of the lines, the slope is 3 and the y-intercept is −2.
Therefore its equation in y = 3x − 2. Now write the equation of the other line.
Use the Equal Values Method to confirm that (1, 1) is the point of intersection.
