Calculate the slope of the line. This is often described as rise over run, or the change in the y coordinates of the two points over the change in x coordinates.If you prefer mathematical symbols, that's usually represented as ∆ y /∆ x . (You read "∆" out loud as "delta," but what it really means is "the change in."). How to find y-intercept with two points

The y-intercept of the line is 250. The plotted line will pass through the y-axis at point 250. Y-Intercept in a Quadratic Equation. Another case where you will encounter y-intercept is in dealing with quadratic equations. In a standard quadratic equation: y = ax 2 + bx + c. The intercept is represented by point c. In the following equation:To begin, let’s determine x and y intercepts using point-slope form. We will begin with an equation: y+2=\frac{1}{2}(x-4) To determine the x-intercept, we must set the value of y equal to zero. Remember, when the line crosses the x-axis, the value of y is always zero. The y-intercept is the y-coordinate when x=0, and the x-intercept is the x-coordinate when y=0. The y-intercept is not in the table. Since the table represents a line, there's a constant rate of change of y with respect to x. So we can find that pattern and fill in skipped values from the table to find the y-intercept.
