Question

Can someone help me with writing the Equation of a Line??

Answer 1

Sure. What are the requirements?

Answer 2

do you know what all the various forms are?

Standard form: \[Ax + By = C\]where \(A,B\) are not equal to 0. Some people require that they should be integers, and relatively prime (meaning no common factors can be divided out of the equation).

Point-slope form: \[y - y_1 = m(x-x_1)\]where \(m\) is slope and \((x_1,y_1)\) is a point the line goes through

Slope-intercept form: \[y = mx+b\]where \(m\) is slope and \(b\) is the y-intercept value

Answer 3

Equation for slope of a line passing through points \((x_1,y_1)\) and \((x_2,y_2)\) is\[m = \frac{y_2-y_1}{x_2-x_1}\]

Answer 4

Have you done your graph yet?

Answer 5

Okay. So the first segment of the line goes from the launch area to point A. What are the coordinates of those two points?

Answer 6

Look at your graph. What are the coordinates of the launch area? What are the coordinates of point A?

Answer 7

You missed a question. One of the most valuable things about math instruction is not learning the Pythagorean theorem, how to add up an infinite sum, or the meaning of cosine, but rather how to read and work carefully and accurately, with good attention to detail. This turns out to be useful in many fields, not just math problem sets :-)

Answer 8

So, I'll ask my two questions again. Please answer them completely:

1) What are the coordinates of the launch area?
2) What are the coordinates of point A?

Your answers should identify what you are answering, not just give some unlabeled information.

Good: "the coordinates of the launch area are (6,7)"
Bad: "(3,4)"
