Question

line v has an equation of y=10/9x +1. Line w includes the point (-3,3) and is perpendicular to line v. What is the equation of line w?

Answer 1

Answer:

y = -9/10x + 3/10 or y = 3/10(1 - 3x)

Step-by-step explanation:

Perpendicular lines have slopes that are negative reciprocals of one another

so slope of line w is -9/10

Using (-3,3) >> y = -9/10x + b

3 = -9/10(-3) + b

3 = 27/10 + b

b = 3 - 27/10 = 30/10 - 27/10 = 3/10

y = -9/10x + 3/10 or y = 3/10(1 - 3x)
