Determining the intersection of 2 direct lines is identical to solving the solution of a two-variable linear equation organization either yesteryear eleminisai method, exchange method or graph method. The next is an illustration of determining the intersection of 2 lines yesteryear the method of elimination too substitution.
Example :
Determine the cutting betoken of the equation of draw of piece of occupation y = 3x + 5 too y = -2x + 15!
Answer:
Elimination y:
5x = 10
5x/5 = 10/5
x = 2
Substitution x = 2 into y = 3x + 5
y = 3x + 5
y = 3(2) + 5
y = half dozen + 5
y = 11
So the intersection of the draw of piece of occupation equation y = 3x + 5 too y = -2x + 15 is (2, 11).
Similarly this article.
Sorry if at that spot is a incorrect word.
