There is only one straight line through two given points.
The slope of this one is [ (y2 - y1)/(x2 - x1) ] = (6-0)/(4-0) = (6/4) = 1.5
If two lines have different slopes, then they intersect at exactly one point. It makes no difference what their y-intercepts are.
Actually it IS. perpendicular lines have opposite reciprocal slopes and parallel lines have the same slope.
Slopes of line perpendicular to the x-axis are undefined.
one
They are the same.
They both have slopes of -3/5 so therefore they are parallel lines
They both have slopes of 3/5 and so it appears that they are parallel lines
If two lines have different slopes, then they intersect at exactly one point. It makes no difference what their y-intercepts are.
To determine the types of lines that pass through the given points, we can find their slopes. The slope between points (1, 2) and (9, 9) is (9 - 2) / (9 - 1) = 7/8, while the slope between (0, 12) and (7, 4) is (4 - 12) / (7 - 0) = -8/7. Since the slopes are different, the lines passing through these pairs of points are not parallel and represent two distinct linear equations on the grid.
To find the slope, you must have at least two points, not one. You cannot find the slope at one point, because coordinate points do not have slopes - lines have slopes.
If the lines are perpendicular, their slopes are negative reciprocals.If the lines are perpendicular, their slopes are negative reciprocals.If the lines are perpendicular, their slopes are negative reciprocals.If the lines are perpendicular, their slopes are negative reciprocals.
negative reciprocal slopes ---> the lines are perpendicular equal slopes ---> the lines are parallel
The slopes of parallel lines are by definition equal.
The slopes of two parallel lines will be the same.
Points: (-2, 7) and (3, 6) the slope is -1/5 Points: (4, 2) and (9, 1) the slope is -1/5 Both slopes are the same and so therefore they are parallel lines
there are 6 lines can pass through 4 noncollinear points.
Areas of equal elevation are connected by contour lines on a topographic map. These lines represent points that share the same altitude, allowing for the visualization of terrain features such as hills, valleys, and slopes. By following these lines, one can trace pathways of equal elevation across the landscape.
