Four times a number added to 3 times a larger number is 31. Seven subtracted from the larger number is equal to twice the smaller number. Let x represent the smaller number and y represent the larger number. Which equations
represent this situation?
O y--gx+31
y - 2x + 7
4.
31
y = 2x+7
o y=-3x+31
y=-2x+7
4.
31
y=-3x+ 3

72 is the answer to this problem

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
