Dick said:Ok so let (x,y) be a point on your curve. That makes it (x,x^2+4), right? Now find the slope of the line between that point and (1,-2). That slope should be your 2x, also right? Now solve for x.
Meeker said:Alright. Once I find x, what do I do with it?.
Btw, the slope for that line is (x-1)/(x^2+6) rite?
The process for finding the equation of two intersecting lines involves identifying the slope and y-intercept of each line, setting the equations equal to each other, and solving for the point where they intersect.
The slope of a line can be found by taking the change in y coordinates over the change in x coordinates, also known as rise over run. This can be calculated by using the formula (y2-y1)/(x2-x1), where (x1,y1) and (x2,y2) are two points on the line.
The formula for finding the y-intercept of a line is y = mx + b, where m is the slope and b is the y-intercept. The y-intercept is the point where the line crosses the y-axis.
No, two lines with the same slope will never intersect. This is because parallel lines have the same slope and will never cross each other.
A linear equation is a straight line with a constant slope, while a non-linear equation does not have a constant slope and can have a curved or non-linear shape.
