1determine whether the slope of each line is positive,negative,zero,or undefined.1.the line passes through the points (a,d) and (a,c)2.the line passes through the points (x,y) and (x+a,y+a)3.the line passes through points (-x,y) and (x,-y)第一题我打错了 应该是1.the lin...

For y=2, you are dealing with ahorizontalline, at y=2. This one does fit your y=mx+b format, but m=0. The slope of this line is 0. All vertical lines are parallel to each other, as are all horizontal lines. If you have one of each, as you do above, those lines will bepe...
is called the slope-intercept form of the equation of a straight line. Because, as we can prove (Topic 9 of Precalculus): a is the slope of the line and b is the y-intercept.Problem 4. What number is the slope of each line, and what is the meaning of each slope?
The properties of an elevation surface can be used to determine the slope of each segment along a line feature across the surface using the tool. For example, calculating the slope of a hiking trail
In the example below, you’ll see that the line has two points each indicated as an ordered pair. The point(0,2)(0,2)is indicated as Point 1, and(−2,6)(−2,6)as Point 2. So you are going to move from Point 1 to Point 2. A triangle is drawn in above the line to he...
-1. if the equations of the two lines are given by ax + by + c = 0 and a’ x + b’ y + c’ = 0, then they are perpendicular if, aa’+ bb’ = 0. (again, you can arrive at this result if you find the slopes of each line and equate their product to -1.) also, ...
