Question

What is the y-intercept of the line perpendicular to the line y = negative three fourthsx + 5 that includes the point (−3, −3)?

negative three fourths
1
7
negative twenty one fourths

Answer 1

Answer:

$b = 1$

Step-by-step explanation:

$y = -\frac{3}{4}x + 5$

The line perpendicular to this is:

$y = \frac{4}{3}x + b$    (We don't know the y-intercept, but we can solve for it since we have a given ordered pair, (-3, -3))

$-3 = \frac{4}{3}*(-3) + b$    (Simplify)

$-3 = -4 + b$    (Add 4 to both sides)

$b = 1$

Answer 2

Answer:

1

Step-by-step explanation:

m1 = -3/4

m2 = 4/3

y = (4/3)x + c

-3 = (4/3)(-3) + c

-3 = -4 + c

c = -3 + 4

c = 1
