What is the equation of the line that passes through the point 5, 7) and has a slope of -2/5?

y =

Step-by-step explanation:

The formula for the equation of a line is y = mx + b, where m is the slope and be is the y-intercept. We have everything we need except for the b, which is the y intercept. WE have the point (5,7) were x = 5 and y =7 and m = (-2/5) substituting these into the equation will give us that b = 9

After substituting the slope of m and b into the equation, we get the equation above.

answer: 40.95

step-by-step explanation:

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.
