What is the equation of a line perpendicular to

Valentin [98]

Since the given line

$y = \frac{ 1}{4} x - 3$

has slope
$= \frac{1}{4}$

The equation of the line perpendicular to it must have a slope which is the negative reciprocal of ,
$\frac{1}{4}$
The slope of the perpendicular line
$= \frac{ - 1}{ \frac{1}{4} } = - 4$
Using the slope intercept form,

$y = mx + c$
We substitute
$- 4$
This implies that,
$y = - 4x + c$
Since

$(-2,4)$
lies on this line , it must satisfy its equation.

That is

$4 = - 4( - 2) + c$

This implies that

$4 = 8 + c$
$4 - 8 = c$
$c = - 4$

The line therefore has equation,

$y = - 4x - 4$

Find product of 3/8 × 4

Korvikt [17]

Answer:

1 and 1/2 or 1.5

Step-by-step explanation:

3/8 × 4/1 = 3/2 = 1 and 1/2

Result in decimals: 1.5

Calculation steps:

3/8 × 4/1 = (3 × 4)/(8 × 1) = 12/8

12 ÷ 4 = 3

8 ÷ 4 = 2

= 3/2 = 1 and 1/2
