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

Question

a line that contains the point (0, −3) and perpendicular to another line whose slope is 2.

Answer 1

perpendicular slopes are negative reciprocals

the new line has a slope of ... -1/2

Answer 2

I won't give the equation, but here's some advice to help. Turn the slope of 2 into a fraction. Also, the slope of a perpendicular line is always the negative reciprocal. This should give you the slope, and you can graph the line to find the y-intercept, giving you the equations of the lines.

Answer 3

(0, -3), m = -1/2 = -0.5,
Y = mx + b.
m = -0.5.
b = y - mx = -3 - (-0.5)0 = -2.5.

Answer 4

use point-slope for the equation ... y + 3 = -1/2 x

Answer 5

Correction to my Eq; b = y - mx = -3 - (-0 5)0 = -3.

Answer 6

y=-1/2x-3
