A line includes the points (9, -7) and (-6, -2). What is its equation in slope-intercept form?
Rus_ich [418]

Answer:

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

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

<em>m</em> - slope

<em>b </em>- y-intercept

Slope Formula: m=\frac{y_2-y_1}{x_2-x_1}

Step 1: Define

Point (9, -7)

Point (-6, -2)

Step 2: Find slope <em>m</em>

<em />m=\frac{-2-(-7)}{-6-9}<em />

<em />m=\frac{-2+7}{-15}<em />

<em />m=\frac{5}{-15}<em />

<em />m=\frac{-1}{3}<em />

y=\frac{-1}{3}x+b

Step 3: Find y-intercept <em>b</em>

<em />-7=\frac{-1}{3}(9)+b<em />

<em />-7=-3+b<em />

<em />-4=b<em />

<em />

Step 4: Write linear equation in slope-intercept form

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

It's due in like 10 minutes please help me out
Naily [24]

Answer:

it should be x=4

Step-by-step explanation:

The line that is perpendicular to

y

=

−

3

is a horizontal line, because horizontal and vertical lines (

x

- and

y

- axes for example) are perpendicular. Therefore, this line will take the form

x

=

n

where

n

is the

x

-coordinate of the point passed through. The

x

-coordinate of the given ordered pair

(

4

,

−

6

)

is

4

, so the equation must be

x

=

4
