there are infinite possibilities

slope is rise over run, or change in y over change in x

Your x and y intercepts give you two points on the line of the graph. Use these two points in the slope equation m = (y2-y1)/(x2-x1), and that gives you the slope.

You can't. There are an infinite number of lines that pass through the point (-2, 3).They all have different y-intercepts and different slopes.In order to narrow it down to a single line, you have to give more information.One more point would do it.=======================================================Here's the minimum information needed to define a unique line:-- you name 2 points; I find slope, intercept, and all other points.-- you name one point and one intercept ... 'x' or 'y'; I find slope and all other points.-- you name x-intercept and y-intercept; I find slope and all other points.-- you name one point and the slope; I find intercept and all other points.-- you name one intercept and the slope; I find all other points.

The table should give you a set of points. Take two coordinated pairs off the table and use the formula y2 - y1 divided by x2 - x1 (rise over run) to get your slope. Then take the slope and one of your points and plug it into y = mx +b with m being the slope, and b as the y-intercept.

If you mean points of: (-3, 27) and (-2, 79) then it works out as 52 Any other arrangements of the points will give a different slope.

slope is rise over run, or change in y over change in x

Your x and y intercepts give you two points on the line of the graph. Use these two points in the slope equation m = (y2-y1)/(x2-x1), and that gives you the slope.

more data points give you a much closer estimate to the slope of the graph at one single point. The slope of the graph between two points is the average velocity between two points, but with more points present, the data points will be closer together to give you a much closer approximation of the slope at one single point

Draw a line of best fit through the plotted points which will give the y intercept. Draw a right angle triangle under the line which will be the triangles hypotenuse. Divide the vertical units of the triangle by the horizontal units which will give the value of the slope.

-- If they give you one set of 'x' and 'y' coordinates, then you have the location ofone point on the line. One point doesn't have a slope.-- If they give you two sets of 'x' and 'y' coordinates, then you have the locations oftwo points on the line. The slope of the straight line between two points is(the difference between the 'y' values) divided by (the difference between the 'x' values)

You can follow the following steps. * First, you determine the slope between the two points. Just calculate delta-y / delta-x (that is, difference in y-coordinates, divided by the difference in x-coordinates, between the two points). * Next, you use the point-slope formula, to get an equation for the line. You can use any of the two points for this; each of the points will give you an equation that looks different, but the two equations are equivalent, if you do everything correctly. * Finally, solve the resulting equation for "y"; that will give you the equation in slope-intercept form.

The table should give you a set of points. Take two coordinated pairs off the table and use the formula y2 - y1 divided by x2 - x1 (rise over run) to get your slope. Then take the slope and one of your points and plug it into y = mx +b with m being the slope, and b as the y-intercept.

type in =SLOPE(known_y's,known_x's) Ex: =SLOPE(D1:D5,A1:A5) And that will give you your slope You need at least two points on the line, if not more. So in one cell, say D1, you could have a y co-ordinate and in A1 an x cordinate, giving you one point. Then in the other cell pairs, like D2 and A2 you could have the co-ordinates for other points. The above example is getting 5 points. So if you fill in your co-ordinates for the points into the appropriate cells, you can use the formula typed into an empty cell to get the slope: =SLOPE(D1:D5,A1:A5)

Answer 1As for example in the straight line equation of: y = 3x+5 the slope is 3 and the y intercept is 5Answer 2The slope could obtained either by giving two (x,y) points on the line or to give the line (x,y) equation.
