You have to massage the equation around until it's in a standard form, with 'Y' all alone on one side of the equation, and everything else on the other side. It'll look like this:
Y = (S)x + (B). 'S' and 'B' are just numbers.
If you can get the equation of the line into this form, then the number 'S' is the slope of the line, and the number 'B' is the number on the y-axis where the graph of the line crosses that axis.
If you mean: y = 3.8x then the slope is 3.8 with no y intercept
If the equation of a line is in the form ax + by + c = 0 then the slope of the line will be -a/b.
If the slope m is given at a point (xo, yo) of a line, then the equation of the line is given by: y - yo = m(x - xo)
Assuming the point is (3, -6) and the slope 1, the equation is x - y - 9 = 0
If given simply the slope of a line and a point through which it passes, and then told to find the equation of the line, one of the easiest ways of doing so is to use the point-slope formula.
If you mean: y = 3.8x then the slope is 3.8 with no y intercept
y = {slope}x + {y intercept}
If the equation of a line is in the form ax + by + c = 0 then the slope of the line will be -a/b.
If you know the slope of the line that your equation is perpendicular too, you find the negative reciprocal of it and use it as the slope for the line. (negative reciprocal = flip the slope over and change its sign. Ex: a slope of 2 has a negative reciprocal of -1/2. ) Then you use the given point, and put your equation in point-slope form. The general equation for point slope form is Y-y1=m(x-x1) The y1 is the y coordinate of the given point. X1 is the x coordinate of the given point. M is the slope that you found earlier. You now have your equation. If you are asked to put it in slope intercept form, simply distribute the numbers and solve the equation for y.
if a line has a slope of -2 and a point on the line has coordinates of (3, -5) write an equation for the line in point slope form
Here is how to solve it. First, find the slope of the given line. To do this, solve the equation for "y". That will convert the equation to the slope-intercept form. From there, you can immediately read off the slope. Since parallel lines have the same slope, the line you are looking for will have the same slope. Now you need to use the point-slope form of the equation, with the given point, and the slope you just calculated. Finally, solve this equation for "y" to bring it into the requested slope-intercept form.
If the slope m is given at a point (xo, yo) of a line, then the equation of the line is given by: y - yo = m(x - xo)
Here are the key steps:* Find the midpoint of the given line. * Find the slope of the given line. * Divide -1 (minus one) by this slope, to get the slope of the perpendicular line. * Write an equation for a line that goes through the given point, and that has the given slope.
Assuming the point is (3, -6) and the slope 1, the equation is x - y - 9 = 0
