Determine the equation of a line through the point (3,-4) that is perpendicular to the line y=3x+7
Lana71 [14]

Answer:

y = - \frac{1}{3} x - 3

Step-by-step explanation:

The equation of a line in slope- intercept fprm is

y = mx + c ( m is the slope and c the y- intercept )

y = 3x + 7 is in slope- intercept form

with slope m = 3

Given a line with slope m then the slope of a line perpendicular to it is

m_{perpendicular} = - \frac{1}{m} = - \frac{1}{3}, thus

y = - \frac{1}{3} x + c ← is the partial equation of the perpendicular line

To find c substitute (3, - 4) into the partial equation

- 4 = - 1 + c ⇒ c = - 4 + 1 = - 3

y = - \frac{1}{3} x - 3 ← equation of perpendicular line

PolarNik [594]

Answer:

A. 20 B. 25

Step-by-step explanation:

A. Perimeter equals the all the side lengths added together, so 5+5+5+5=20

B. Area equals (for a square) two side lengths multiplied by one another, so 5x5=25
