The points (80, 20) and (120, 30) form a proportional relationship. What is the slope of the line that passes through these points? 14

10 over 40

Step-by-step explanation:

y2-y1 over x2-x1

the correct option is b

step-by-step explanation:

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
