Question

Graph the 3 lines k, l, and m based on the following

information: Line k is parallel to line / and perpendicular to
line m. Line k passes through the origin (0, 0) and has a slope
of ½. Line m intersects line k at the point (4, 2). Line / has a y-
intercept of 4. Graph and label the 3 lines. Circle the letter of
the statement below which is false. Explain why it is false.

Answer 1

Explanation:

If l and k are lines in the xy-plane, is the product of the slopes of l and k equal to -1 ?

(1) Line l passes through the origin and the point (1,2).

(2) Line k has x-intercept 4 and y-intercept 2
