Question

3.Write the equation of the line which passes through (–4, 2) and is parallel to y = –x + 6 in slope-intercept form. (2 point)


4.Write the equation of the line which passes through (2, –3) and is perpendicular to y = 4x + 7 in standard form. (2 point)


5.Using complete sentences, describe one example of a place in your everyday life of parallel lines and one example of perpendicular lines. You may also provide a digital image or self-created picture. (4 points; 2 points for each example)

Answer 1

3. parallel=same slope
y=mx+b , m= -1 , (-4,2)
2=-1(-4)+b
2=4+b
-2=b
so the equation is y=-x-2

Answer 2

for the last one, totally do parallel dimensions :p
Or streets.

Answer 3

For the second problem, Perpendicular means that they form a cross. slope is negative reciprocal- aka a slope of 4 becomes -1/4.
y=mx+b
y=-1/4 x +b
-3=-1/4(2)+b
-3=-1/2 +b
-2.5=b

y=-1/4x -2.5
