To find the slope of a line passing through two points, use the slope formula: (y2 - y1)/(x2 - x1). It's the change in y divided by the change in x, or the "rise over the run." In this case, the (x2, y2) point is (4, 9) and the (x1, y1) point is (-2, 7). The slope of the line is:
(9 - 7)/(4 - -2) = 2/6 = 1/3
Actually, it doesn't matter which point you use as (x2, y2) and (x1, y1). If you did it the other way around you would get the same answer:
(7 - 9)/(-2 - 4) = -2/-6 = 1/3
which equation has a slope of -1/2 and a graph that passes through (-3,4)?
Y=mx+b
It is: y = -2x

The slope is (9 - -1)/(2 - 4) = 10/-2 = -5
which equation has a slope of -1/2 and a graph that passes through (-3,4)?
The line is vertical and so the slope is undefined.
The slope is -2/3.
Write the equation of a line in slope-intercept form that has a slope of -2 and passes through the point (2, -8).
Its called a cut when you slice through a slope
The slope is 1/2.
Y=mx+b

If you mean a slope of -4 passing through (-2, 6) then it works out as y = -4x-2
The slope is 2.
It is: y = -2x
If you mean: (0, 0) and (2, 4) then the slope works out as 2
