Question

Graph the line using a point and a slope. Write the equation of each line.

the line that contains the point (0, −3) and perpendicular to another line whose slope is

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.
