In general you find the equation of the line that passes through those two points. Select one of the points in the row and use the x and y values to find b.
Set x 0 and solve for y.
How to find y intercept from two points. 3 1 333 5 c. Y mx c. The following line passes through the point 5 comma 8 and the equation of the line is y is equal to 17 13x plus b.
Plug the given values into the formula for a slope. Set y to 0 and then solve to find the y intercept. To find the y intercept using the equation of the line plug in 0 for the x variable and solve for y.
Here y2 3. Check your solutions on a graphing calculator if you can to see if they make sense. Substitute b into the equation.
0 x 2 2x 1 setting y to zero x 1 2 using the quadratic formula to solve therefore there are two intercepts at 1 2 0 and 1 2 0. You find this by taking one of your coordinates 3 4 and you substitute it into the equation y mx c. Find the slope intercept form of the points 2 1 5 3.
For example two points are 3 5 and 6 11 substitute the slope m in the slope intercept form of the equation. Find the slope m. You can use the formula to find the inclination between two points.
M 7 5 3 1 1 2. Your y intercept is where the line your two points make crosses the y axis. How do you find the y intercept when given two points.
Substitute either point into the equation. M 4 3. This will give you y 3x b.
Calculate the slope from 2 points. M y2 y1 x2 x1. So we know that this point this x and y value must satisfy this equation so we know that when x is equal to 5 y is equal to 8.
The following line passes through the point 5 comma 8 and the equation of the line is y is equal to 17 13x plus b. You can use either 3 5 or 6 11. What is the value of the y intercept b.
Now the y intercept is b y 1 m x 1 or b y 2 m x 2 the result is the same. M 3 1 5 2. The slope of a line passing through two points p x 1 y 1 and q x 2 y 2 is given by m y 2 y 1 x 2 x 1.
We have that x 1 1 y 1 5 x 2 3 y 2 7. Solve for b which is the y intercept of the line. Simply and you ll get.
Equation and see if it reaches the correct y value. Calculate the slope from two points with formula. If then two points have the same x coordinate then there is no y intercept.
So we can say so when x is equal to 5 y is equal to 8. To find the y intercept using the equation of the line plug in 0 for the x variable and solve for y. Of the two points have the same y coordinate then the y intercept would be that same value.
If you know the slope connect it m in y mx b. If the equation is written in the slope intercept form plug in the slope and the x and y coordinates for a point on the line to solve for y. How to find y intercept with two points.
Find out the y intercept by entering the values of slope y and x in equation.
