If k is an explanatory variable and / is the corresponding response variable, which of these would be represented by the horizontal axis on a scatterplot?

I'm pretty sure it's b). i try drawing the functions out and b is the one that stands out or isnt a "line"

Cis your correct answer

This polygon has 4 sides
180(4-2) = 180(2) = 360 degree
80+90+2x + 3x = 360
170+5x = 360
5x = 190
x= 38
measure of angle t is 2(38)= 76
the answer is c. trust me
hope this !
