True or false: if jk has endpoints j(7,0) and k(-5,-4) then the midpoint lies in quadrant iv

True.

Step-by-step explanation:

THe midpoint is (7 + (-5)) / 2 ,   (0 -4)/2

= 2/2, -4/2

= (1, -2)   which is in the quadrant IV , so it's true.

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b

d is the only accurate one
