Write an equation of the line that passes through the points (-1,-2) and (5,1)

y = x -

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (- 1, - 2) and (x₂, y₂ ) = (5, 1)

m = = = , hence

y = x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (- 1, - 2 ), then

- 2 = - + c ⇒ c = - 2 + = -

y = x - ← is the equation of the line

1^3 + 2^3 + 3^3 +4^3 = (1+2+3+4)^2
