#intersect function

Introduction in consideration of intersect function:<\p>

Taper mystery is one touching the basis of mathematics. Intersect perk is defined as an instance where two supporting role or two points intersect each and every other. Synchronism of two lines are defined as the where the two lines intersect. Close with function hack it also be familiar with for planes in geometry, shapes used good terms mathematics. For example, the intersection of duo points can be represented as<\p>

To illustrate problem for sing in chorus desire<\p>

Example 1: Find the correspondence point parce que the assumption two-line which flit through the point ( 1, 2 ) and ( 2, 3 ) the queue up ( 2,3 ) and ( 3,4 ).<\p>

Solution:<\p>

Strolling gait 1: For espial the intersection point as for two lines we have to find the slope for the apt lines.<\p>

Accomplishment 2: The slope for the giftlike line is given wherewith,<\p>

m = `(y_(2)-y_(1))\(x_(2)-x_(1))`<\p>

Step 3: Open arms the given points, the value of x1= 1, y1 = 2 and x2 = 2, y2= 3<\p>

Step 4: Substituting the values in the slope equation we have,<\p>

m = `(3-2)\(2-1)`<\p>

= 1<\p>

Step 5: By putting in the levelness format, we have,<\p>

y - 2 = 1( x - 2)<\p>

x - y = 0 -----------------><\p>

Motion 6: For the no such thing line we have tenure of the points, x1 = 2, y1 = 3 and x2 = 3, y2 = 4.<\p>

Step 7: In step with substituting the levelness in slope formula, we acquire,<\p>

m = `(y_(2)-y_(1))\(x_(2)-x_(1))`<\p>

Step 8: Substituting the values access the above formula, we have<\p>

m = `(4-3)\(3-1)`<\p>

= `(1)\(2)`<\p>

Estimate 8: Substituting the m value gangway the factor we have,<\p>

y - 4 = `(1)\(2)` ( mark - 3)<\p>

2y - 8 = x - 3<\p>

x - 2y = 5 ------------------><\p>

Resign 9: Solving the above two equations, we see,<\p>

x - y =0<\p>

cross patee - 2y = 5<\p>

Strolling gait 10: By solving the difference we get, the point of intersection is, ( -5, -5 ).<\p>

Another defect for intersect function<\p>

Example 2: Find the crossroad point as to two-line, whether it's in the identical point for the given equations, 3 + 2x = y and 6 - 4x = y.<\p>

Solution:<\p>

Rack 1: For the assumption equations, we are movement to find the value referring to x and y.<\p>

Step 2: For solve for the value x by equating the two equations given, we get,<\p>

2x + 3 = 4x - 6<\p>

4x - 2x = -6-3<\p>

2x = - 9<\p>

x = - `(9)\(2)`<\p>

Step 2: By substituting this value in either one of the divisor we get,<\p>

3 + 2x = y<\p>

3 + 2( - `(9)\(2)` ) = y<\p>

y =6<\p>
