Which lines are perpendicular to the line y – 1 = (x+2)? check all that apply.

y + 2 = –3(x – 4)

y − 5 = 3(x + 11)

y = -3x –

y = x – 2

3x + y = 7

none of them

Step-by-step explanation:

The given line is, written in a more convenient way:

I moved the (-1) to the right hand side, it became (+1) and summed with (+2) gave the (+3).

As you can see, the slope of your line is +1.

Now what do we know from the theory? We know that two lines are perpendicular if one's slope is the negative periodical of the other's.

In your case this is very easy to calculate. The negative reciprocal of +1 is -1.

The slopes of the five cases given as options are as follows:

1) -3

2) +3

3) -3

4) +1

5) -3

None of those lines is perpendicular to the original given line.

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
