What is an equatiom for the line with slope 2/3 and y-intercept 9

y = (2/3)x + 9

Step-by-step explanation:

Equation of a straight line is y = mx + b. You are trying to finish the equation.

Note that:

m = slope = 2/3

b = y-intercept = 9

Plug in the corresponding numbers to the corresponding variables:

y = mx + b --> y = (2/3)x + 9

y = (2/3)x + 9 is your equation.

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
