lesson 1 - correct answers✅slope and parallel lines
examine the following lines and answer the question.
given that line a is parallel to line b and the slope of line a
is 2, what is the slope of line b? - correct answers✅2
line l contains the points a(-2, 2) and b(-1, 0), and line k
contains the points c(0, 4) and d(1, 2)
are lines l and k, parallel? justify your response. - correct
answers✅yes, both lines have a slope of -2, so they are
parallel.
use the diagram to answer the question. if cyrus knows
that abc ~ edc and ab || ed, how can he prove that like m
passing through ab has the same slope as line l passing
through ed? - correct answers✅cyrus can use
properties of similar triangles to show that ac/ec = bc/dc.
then, by the multiplication property of equality, ac/bc =
ec/dc. by the slope formula, the slope of line m = -ac/bc
and the slope of line l = -ec/dc. thus, the slopes are
equal.

which equation in slope-intercept form represents a line
that passes through the point (5, -1) and is parallel to the
line y = 2x - 7? - correct answers✅y = 2x - 11
which equation in slope-intercept form represents a line
that passes through the point (2, 3) and is parallel to the
line y - 9 = 2/3(x + 7)? - correct answers✅y = 2/3x +
5/3
allana knows that xyz ~ uvz and xy || uv. what segment
relationships can allana use to prove that the slope of line
l is equal to the slope of line m? - correct
answers✅allana can show that uz/xz = vz/yz using the
properties of similar triangles. then, uz/vz = xz/yz by the
multiplicative property of equality. so, the slopes are
equal by the slope formula.
which equation in slope-intercept form represents a line
that is parallel to y = 1/2x - 2 and passes through the
point (-8, 1)? - correct answers✅y = 1/2x + 5
which equation in slope-intercept form represents a line
that is parallel to y = -4x - 5 and passes through the point
(0, 0)? - correct answers✅y = -4x

line l contains the points a(2, 2) and b(3, 6). line k
contains the points c(0, 5) and d(1, 9).
are lines l and k parallel? justify your response. - correct
answers✅yes, lines l and k are parallel because the
slopes are equal.
examine the two distinct lines defined by the following
two equations in slope-intercept form.
are lines l and k parallel? justify your response. - correct
answers✅yes lines l and k are parallel because their
slopes are equal.
