**What in the world is y = y1 + b (x x1) ? Yahoo Answers**

linear equation n. An algebraic equation, such as y = 2x + 7 or 3x + 2y - z = 4, in which the highest degree term in the variable or variables is of the first degree. The graph of such an equation is a straight line if there are two variables. linear equation n (Mathematics) a polynomial equation of the first degree, such as x + y = 7 lin?ear... Using the point-slope form y - y1 = m (x-x1) write an equation for the line with slope -2, containing the point (3,4) 7 write an equation in point-slope form for the line through the given point with the given slope (4, -6); m = 3 over 5

**How do you create the linear equation with only two points**

y-y1 = m(x-x1) is the slope formula to be used in both problems. For the first problem I will show the math to find the a line parallel to y= -1/3x – 4, that passes through the ordered pair (-6, -3)....The slope intercept formula is y=mx + b in which m is the coefficent by x, x is the slope, and b is the y-intercept which is why it is called y-intercpet or slope-intercept.

15/09/2008 · Best Answer: That's called the point-slope form for the equation of a line. You use it when you know the slope of a line and one point on it. y - y1 = m(x - x1) m is the slope, (x1, y1) is the point. In your problem, you just plug in the numbers: m = -2/3 (x1, y1) = (6, 1) So, y - 1 = (-2/3)(x - 6) The rest how to use a computer step by step 1/08/2011 · What you want to use is the point-slope formula which is basically y - y1 = m(x - x1). In this formula, it really does not matter which point you pick, just …. How to use the foil method in algebra

## How To Use The Formula Y-y1 M X-x1

### 6/07/2008 · the ordered pair is (4,-3) (-1,7). I know I have to use m=y2-y1 over x2-x1 to find the slope. My textbooks says to use y-y1=m(x-x1) to write the equation of a line connecting the given points in slope-intercept form.

- 2/09/2008 · Best Answer: y = y1 + b (x - x1) is a point slope formula. It is also in the form y - y1 = m (x - x1). There is also a 2 point formula where you substitute m = (y2 - y1) / (x2 - x1). This is consistent with the points you were given as (1-5) / (4-2) = -2. This is the slope you were given. Therefore, (x1,y1
- Use the slope formula to determine the slope of the line that passes through the points A(-5, 9) and B(-5, 6). Answer provided by our tutors The "point-slope" form of the equation of a straight line is:
- 18/01/2012 · it gives you the equation of any line if you knwo the gradient (m) and any point on that line co-ordinates (x1, y1) x1 is the x co ordinate of the point and y1 is the y co ordinate of hep oint. sub allthis info into that formual and it will give u a linear equation.
- I always use y-y1=m(x-x1). I like the way once you've remembered that you don't need to remember anything else... apart from everything else. I like the way once you've remembered that you don't need to remember anything else... apart from everything else.
