A line is perpendicular to y = -2x - 1 and intersects the point (6,9).
What is the equation of this
perpendicular line?
y = 2x + [?]

y = 2x + [-3]

Step-by-step explanation:

Slope of the perpendicular line = m = 2

Point = (x,y) = (6,9)

So, x = 6, y = 9

Putting in slope intercept equation

9 = (2)(6) + c

c = 9-12

c = -3

Putting m and c in slope intercept equation

y = 2x + [-3]

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)
