In the x y-coordinate plane above, line l contains the points (0 comma 0) and (1 comma 2). If line m (not shown) contains the point (0 comma 0) and is perpendicular to l, what is an equation of m?
Can you resolve this problem?
+128475 The slope of the first line, l, is given by :
[2 - 0 ] / [1 - 0 ] = 2
Line m will have a negative reciprocal slope = -1/2
And since this line contains the point (0, 0 ) , its equation is just y = (-1/2)x
Here's the graph of both lines.........https://www.desmos.com/calculator/ryqoh2tezn
