The features of the eaves polygons the roofing cross-lines, the dinations of cross-lines,the roofing vertexes,the roofing polygons and the drawing method about straight projection drafting of the roofing with the same slope are stated in this paper. 本文阐述了同坡屋顶的屋檐多边形、屋面交线、...
Determine whether the pair of lines are parallel or perpendicular. {eq}6 x = 5y + 1 {/eq} and {eq}-12 x + 10 y = 1 {/eq} Parallel and Perpendicular Lines: Lines that do not intersect are parallel to each other and share the same slope but different intercepts...
In the case where one of the lines is vertical, the slope of that line is undefined and it is not possible to calculate the product with an undefined number. When one line is vertical, the line perpendicular to it will be horizontal, having a slope of zero (m=0m=0)....

They may be the same line (but with a different equation), and so are not parallel.How do we know if they are really the same line? Check their y-intercepts (where they cross the y-axis) as well as their slope:Example: is y = 3x + 2 parallel to y − 2 = 3x ? For y =...

1. Identify the slopes of the given lines: The equations of the lines can be rearranged into slope-intercept form y=mx+c: - For the line 3x−y−3=0: y=3x−3 The slope m1=3. - For the line 3x−y+5=0: y=3x+5 The slope m2=3. Since both lines have the same slope,...
flat, we do not expect the ball to roll as much. However, as we slowly replace the line each time with a steeper one, we can observe that the ball rolls faster as the steepness of the line increases. In this regard, we get a gist of how the concept of the slope is relevant for...
