Are the Lines Parallel? How do you know?
Line 1 runs through the points (-6, 6) and (0, 5)
Line 2 runs through the points (0, -3) and (6, -4)
Yes, their slopes are opposite reciprocals
Yes, their slopes are the same
No, their slopes are opposite reciprocals
No, their slope are the same
Which of the following lines goes through the point (0, 4) and is PARALLEL to y = 5x - 3?
HINT: PLUG (0,4) AND THE PARALLEL SLOPE INTO y=mx+b. SOLVE FOR b AND REWRITE THE EQUATION IN y=mx+b.
y = 1/5x - 3
y= 5x - 7
y = 5x + 4
y = -5x - 3
Which of the following lines goes through the point (-3, 4) and is PERPENDICULAR to y = 3/2x + 6?
HINT: PLUG (-3,4) AND THE PERPENDICULAR SLOPE INTO y=mx+b. SOLVE FOR b AND REWRITE THE EQUATION IN y=mx+b.
y = 3/2x - 6
y = 2/3x + 3
y = -2/3x - 2
y = -2/3x + 2
Write the equation of a line that passes through the point (2, 6) and is PERPENDICULAR to the line y = -4x + 8.
HINT: PLUG (2,6) AND THE PERPENDICULAR SLOPE INTO y=mx+b. SOLVE FOR b AND REWRITE THE EQUATION IN y=mx+b.
y = 1/4x + 5.5
y = 4x + 6
y = -1/4x + 8
y = -4x + 8
