The easiest way is to find the equations of the two lines and then calculate the intersection.

How to find the point of intersection with y=mx+b. The system of equations. Y -05x 7. This point must lie on the target line.

The y-coordinate for Line 2 is calculated this way. Results in the quadratic equation. By the argument above if the line passes through the circle again the other point of intersection must also be rational.

The y-coordinate for Line 1 is calculated this way. Public static int FindIntersectionPoint int p0 int p1 int p2 int p3 line 1 equation double m1 double Mathabs p0 1 - p1 1 double Mathabs p0 0 - p1 0. The value of b is the y -intercept that is the point where the line crosses the y -axis.

0 -b 8-b 8. Now I find it annoying sometimes when trying to find where two lines intersect I have two pull out a sheet of graph paper and plot them or make a table. Calculate where the line intersects with the y-axis by entering one of the coordinates into this equation.

So you can solve for the constants m and b. Find the locus of point of intersection of lines y mx sqrta2m2 b2 and my - x sqrta2 m2b2 The point of intersection say hk must satisfy both the equation. For one line you have two points which gives two equations.

Calculate the slope y 2 - y 1 x 2 - x 1 Step 2. So at the point of intersection the x y coordinates for Line 1 equal the x y coordinates for Line 2. Which has all rational coefficients.

Therefore the target line is 2x 3y 12 or dividing by 12 x6 y4 1. Y mx b where m is the slope of the line and b is the y-intercept. Line 2 equation double m2 double.

The line x - y 8 will intersect the y-axis when x 0 since every point on the y-axis has an x-coordinate of 0 ie x y 0 b where y b when x 0. Equations in the form y mx b represent lines in the xy -plane. A 6 b 4.

Since at the point of intersection the two y-coordinates are equal well get to the x-coordinates in a moment lets set the y-coordinate from Line 1 equal to the y-coordinate from Line 2. X 2 mx b 2 25. Using one of the original coordinates 7 4 we find the y-axis intercept b using the formula.

Suppose that two lines have the equations y a x c displaystyle yaxc and y b x. The equation of any straight line called a linear equation can be written as. To calculate the slope-intercept equation for a line that includes the two points 7 4 and 1 1.

That is have them in this form. Therefore to find the point of intersection 0 b between the line x - y 8 and the y-axis we set x 0 and then solve for y b as follows. The value of m is the slope of the line ie the rise over the run.

X 2 y 2 25 y mx b. The x displaystyle x and y displaystyle y coordinates of the point of intersection of two non-vertical lines can easily be found using the following substitutions and rearrangements. Struggling to find point of intersection using two lines in y mx b form.

X - y 8. If two lines have distinct slopes then they will have a unique intersection point. Substituting in 1 c 12.

Y mx b. This is a sensible equation that can also be named as the slope-intercept form. Y axis intercept DCdrawLine p0 0 p0 1 p1 0 p1 1.

Slope double b1 p0 1 - m1 p0 0. Imagine any line y mx b with rational slope that passes through our circle at a rational point. For the equation y mx b m is the slope of the line that is multiplied by x and b is the y-intercept or we can say the point where the line will cross the vertical y-axis.

Suppose I have these two algebraic equations in the format ymxb. The locus of point of intersection of the lines y mx a2m2b2 and my - x a2b2m2 is. Slope Intercept Form Formula.

Get the two equations for the lines into slope-intercept form. The equation of a line is given by y mx b where m is the slope and b is the y-intercept. Y 2x 3.

Slope m 1 - 4 1 - 7 -3 -6. Slope m -3-6 12. Y2x4 y3x5 Now by graphing these two algebraic equations on a coordinate plane I find that they intersect at the point -12.

0 - b 8. The point of intersection of the two given lines can be obtained by solving the two simultaneous linear equations in x and y the result is x 3 y 2. Set the two equations for y equal to each other.
