Write the point slope form of the equation for a line that’s passes through (-1,4) with a slope of 2

The answer is

Step-by-step explanation:

To find an equation of a line given the slope and a point we use the formula

where

m is the slope

( x1 , y1) is the point

From the question the slope is 2 and the point is ( - 1 , 4)

The equation in point slope form is

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.
