How Do I Find the Point of Intersection of Two Lines?

  1. Get the two equations for the lines into slope-intercept form.
  2. Set the two equations for y equal to each other.
  3. Solve for x.
  4. Use this x-coordinate and substitute it into either of the original equations for the lines and solve for y.

How do you find the intersection of two sets of points?

To find the point of intersection algebraically, solve each equation for y, set the two expressions for y equal to each other, solve for x, and plug the value of x into either of the original equations to find the corresponding y-value. The values of x and y are the x- and y-values of the point of intersection.

What is the point of intersection of the line 3x 2y 6 and the y-axis?

Hence, the line 3x – 2y = 6 cuts y-axis at the point (0,-3).

For what value of k do the equations 3x y 8 0 and 6x KY 16 0 represent coincident lines?

Answer: For k = 2, the two equations 3x-y+8=0 and 6x-ky=-16 represent coincident lines.

How do you find the intersection of a line and circle?

Intersection of a line and circle 1 If the line cuts through the circle, there will be two points of intersection 2 If the line is a tangent to the circle, there will be one point of intersection 3 If the line misses the circle, there will be no point of intersection

How do you find the X-values for lines that intersect at two points?

Here’s how to find the two x-values for lines that intersect at two points: Example (factoring): We ended up with the equation (x−2)(x+3)=0{\\displaystyle (x-2)(x+3)=0}. If either of the factors in parentheses equal 0, the equation is true. One solution is x−2=0{\\displaystyle x-2=0} → x=2{\\displaystyle x=2}.

How to find the X and Y coordinates of the intersection?

This will be the x coordinate of the intersection point. Then you can find the y coordinate of the intersection by filling in the x coordinate in the expression of either of the two lines. Since it is an intersection point both will give the same y coordinate.

What is the intersection of Y = 3*11 + 2?

We get y = 3*11 + 2 = 35. So the intersection is at (7,11). If we check the second expression y = 4x – 9 = 4*11 -9 = 35. So indeed we see that the point (7,11) also lies on the second line. In the picture below, the intersection is visualized.
