SOLUTION: How do you write an equation of the line that passes through the point (4, 7) and is perpendicular to the line y = 0.5x � 1

Question 692862: How do you write an equation of the line that passes through the point (4, 7) and
is perpendicular to the line y = 0.5x � 1
Answer by jim_thompson5910(35256) (Show Source): You can put this solution on YOUR website!
perpendicular slope: 2

y = mx + b

y = 2x + b

7 = 2(4) + b

7 = 8 + b

7 - 8 = b

-1 = b

b = -1

m = 2, b = -1

Answer: y = 2x - 1
