In the standard x, y coordinate plane, what is the midpoint of the line segment that has endpoint 3,8 and 1,-4

the answer would be 2

Step-by-step explanation:

The question is what is the value of 8x-3 over x and the answer to that question is 2 and hears why (8x multiplying by 1/2)-3 over 1\2 = 4 - 3 over 1/2 and half of 8 is 4 so 1 over 1/2 = 1 x 2 over 1 x 1 = 2

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

c
