Which function has an inverse that is also a function?
{(-4, 3), (-2, 7), (-1, 0), (4, -3), (11, -7)}
{(-4, 6), (-2, 2), (-1, 6), (4, 2), (11, 2)}
{(-4,5), (-2, 9), (-1, 8), (4, 8), (11, 4)}
{(-4,4), (-2,-1), (-1,0), (4, 1), (11, 1)}

step-by-step explanation:

the shape,the size and the distance

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

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 ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

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

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form

i believe that the answer is

b. y-1=-2(x-4)

hope this !
