A recipe for lasagna calls for 4 lbs of tomatoes to serve 9 people. A caterer wants to make enough lasagna to serve 115 people. How many lbs of tomatoes does he need

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
