line (8,-9),(-4,15)

Solution

line

(8, - 9), (- 4, 15)

Solution

y = - 2 x + 7

Solution steps

Find the line

y = mx + b

passing through

(8, - 9)

,

(- 4, 15)

Compute the slope

(8, - 9), (- 4, 15) : m = - 2

Compute the

y

intercept:

b = 7

Construct the line equation

y = mx + b

where

m = - 2

and

b = 7

y = - 2 x + 7

Popular Examples

intercepts of y=x^2 intercepts

y = x^{2}

shift f(x)=2sin(2/3 x-pi/6)shift

f (x) = 2 sin (\frac{2}{3} x - \frac{π}{6})

extreme f(x)=(x+4)(x-1)^2 extreme points

f (x) = (x + 4) (x - 1)^{2}

domain of f(x)=(x^2-3x)/(x+4)domain

f (x) = \frac{x ^{2} - 3 x}{x + 4}

slope ofintercept y=3x-5 slope intercept

y = 3 x - 5
