Perpendicular lines have negative reciprocals. This means that if you multiply the slopes of both lines, the product will be a -1.

In your given point-slope equation, the slope is 1/3. Therefore, the negative reciprocal of 1/3 must be -3.

Out of the given options:

y + 2 = -3(x — 4)
y = -3x - 5

are the linear equations that are perpendicular to y — 1 = 1/3(x + 2).

Therefore, the correct answers are Options 1 and 3.

It is given that p varies inversely as q. If p = 12 and q = 45 find p, if q is 135.
alexgriva [62]

Answer:

p =4

Step-by-step explanation:

Given

Variation: Inversely

p = 12 when q = 45

Required

Determine p when q = 135

First, we need to determine the relationship between p and q

Since, it is an inverse variation.

The relationship is:

p\ \alpha\ \frac{1}{q}

Convert to an equation

p= k *\frac{1}{q}

p= \frac{k}{q}

Where k = constant of variation

Make k the subject

k = p * q

When p = 12 and q = 45

k = 12 * 45

k = 540

To solve for p when q = 135

Substitute 135 for q and 540 for k in p= \frac{k}{q}

p = \frac{540}{135}

p =4
