Finding the Y-Intercept from Slope and Point

The video tutorial explains how to find the y-intercept of a line given its equation and a point through which it passes. By substituting the point (5, 8) into the equation y = 17/13x + b, the tutorial demonstrates the steps to solve for the y-intercept b. The process involves substituting the x and y values, simplifying the expression, and solving for b, resulting in the final line equation y = 17/13x + 19/13.

What is the given point through which the line passes?

• 3, 7

• 2, 4

• 5, 8

• 6, 9
