Question

One line passes through the points (-2, 1) and (4,9). Another line passes through points (-3, 8) and (5,2).
Are the lines parallel, perpendicular, or neither?
A.Parallel
B.Perpendicular
C.Neither

Answer 1

Answer:

First, put the equation of the line given into slope-intercept form by solving for y. You get y = 2x +5, so the slope is –2. Perpendicular lines have opposite-reciprocal slopes, so the slope of the line we want to find is 1/2. Plugging in the point given into the equation y = 1/2x + b and solving for b, we get b = 6.
