How to find y intercept given two points. Things To Know About How to find y intercept given two points.

Mar 15, 2022 ... Question: To find an equation for a line between two points, you need two things. 1. The y-intercept of the graph. 2. The slope of the line.The y-intercept is the point where a line or curve intersects the y-axis. It is denoted by the coordinate (0,b), where “b” represents the y-value at which the line intersects the axis. It is also referred to as the starting point or initial value. For example, in the equation y = 2x + 5, the y-intercept is 5, and the slope is 2.That's why moving from an x-value of -1 to 0 will move you down by 2/3 (from a y-value 2 to 4/3, because 2 - 2/3 is 4/3. This can also be written as 6/3 - 2/3 = 4/3) Another way to do this is by plugging the slope and a point to the slope-intercept equation (y = mx + b) to solve for the y-intercept.To algebraically find the intersection of two straight lines, write the equation for each line with y on the left side. Next, write down the right sides of the equation so that they are equal to each other and solve for x. Write down one of the two equations again, substituting the previous answer in place of x, and solve for y.

Summary. To find the intersection between two lines y = ax + b and y = cx + d the first step that must be done is to set ax + b equal to cx + d. Then solve this equation for x. This will be the x coordinate of the intersection point.The point-slope form is y−y_0=m (x-x_0) y − y0 = m(x− x0).
