line (-2,1),(1,-8)

Solution

line

(- 2, 1), (1, - 8)

Solution

y = - 3 x - 5

Solution steps

Find the line

y = mx + b

passing through

(- 2, 1)

,

(1, - 8)

Compute the slope

(- 2, 1), (1, - 8) : m = - 3

Compute the

y

intercept:

b = - 5

Construct the line equation

y = mx + b

where

m = - 3

and

b = - 5

y = - 3 x - 5

Popular Examples

inverse of f(x)=x^2-4x+10 inverse

f (x) = x^{2} - 4 x + 10

asymptotes of f(x)=(x^2-81)/(x-9)asymptotes

f (x) = \frac{x ^{2} - 81}{x - 9}

parity f(x)=tan(x*2)-x parity

f (x) = tan (x \cdot 2) - x

critical f(x)=4+1/3 x-1/2 x^2 critical points

f (x) = 4 + \frac{1}{3} x - \frac{1}{2} x^{2}

f (x) = x + 2
