On the coordinate plan, what is the distance between the points (−3, −7) and (−9, −7)?

A) 5
B) 6
C) 12
D) 14

the answer is 6

Step-by-step explanation:

let pt(i)= (-3,-7) and pt(i) =(-9,-7)

=(x1, y1) =(x2, y2)

form the formula

d=√(x2 - x1)² + (y2-y1)²

d=√ (-9 - -3)² + (-7 - -7)²

d=√ (-6)² + 0²

d=√36

d=6units

the distance is 6 units

x=30

step-by-step explanation:

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get
