Answer: y = 4/3x
y = -3/4x + 1 ⇔ 3x + 4y - 4 = 0
have:
(d): perpendicular to 3x + 4y - 4 = 0
contains the point (9;12)
=> (d): 4x - 3y + 3.12 - 4.9 = 0 ⇔ 4x - 3y = 0 ⇔ y = 4/3.x
Step-by-step explanation:
Answer:
y = (4/3)x
Step-by-step explanation:
You have to find the y-intercept, b. Do this by substituting in the x and y values into the equation:
12 = (4/3)(9) + b
12 = 12 + b
b = 0
So, y = (4/3)x
Hope that helps! :D
