What I the slope of a line that is perpendicular to the line 2y-3x=8
Zolol [24]

<u>ANSWER</u>

-  \frac{2}{3}

<u>EXPLANATION</u>

The given given equation is

2y - 3x = 8

We need to rewrite this equation in the slope-intercept form:

y = mx + b

We add 3x to both sides.

2y  - 3x + 3x=8  + 3x

\implies \: 2y  =  3x + 8

We divide through by 2 to get,

y =  \frac{3}{2}x + 4

The slope of this line is

m =  \frac{3}{2}

Let the slope of the line perpendicular to this line be 'n' .

Then the product of the slopes of two perpendicular lines is always negative 1.

m \times n =  - 1

\implies \:  \frac{3}{2} n =  - 1

\implies \:   \frac{2}{3}   \times \frac{3}{2}n =  - 1 \times  \frac{2}{3}

n =  -  \frac{2}{3}

Therefore the slope of the new line is

-  \frac{2}{3}

The measure of angle 1 is (3x + 10º and the measure of angle 4 is (4x - 15) What is the measure of angle 7?
sladkih [1.3K]
On a typical number line, we have basically two directions that we can move on. Either to the left where the numbers are negative, of to the right where the numbers are positive.
Given that point E has a coordinate of 1 on a number line, and we are told that the distance between E and another point on the number line is 11 (EG), the possible coordinates of point G are two (either we are moving to the right or to the left). Therefore, possible coordinates of G are:
1 - 11 = -10 (to the left)
1 + 11 = 12 (to the right
