Which equation represents a line perpendicular to the line shown on the graph?

Vadim26 [7]

Answer:

See description below.

Step-by-step explanation:

To choose the correct equation, find the slope of the line on the graph. Identify two points on the line. Then subtract to find their rate of change using the slope formula.

$m=\frac{y_2-y_1}{x_2-x_1}$

When you know the slope, find the negative reciprocal. For example, if the slope is 2/1 then the negative reciprocal is -1/2. This is the slope of a perpendicular line to a line with slope 2. Choose the equation which has this same slope.

Example:

y = 2x -1

y= -1/2 +5

I don't understand number 8

Norma-Jean [14]

Let's try plugging in some negative numbers. Let's do x=-1. 5+-1=4. So we know that if we put in a negative number for x, then n will be positive. But what if we do a number greater than -5, because 5+-5=0. So let's try x=-6. So 5+(-6)=-1. Hmm. So here it is. We know that any number under -5 will be positive and any number above -5 will be negative.

DerKrebs [107]

Answer:

1/4.

Step-by-step explanation:

That is 1 - (1/4 + 2/5 + 1/10).

The Lowest common multiple 4 5 and 10 is 20 so we have

20/20 - (5/20 + 8/20 + 2/20)

= 20/20 - 15/20

= 5/20

= 1/4 answer.
