Identify the system of equations that have the point (3,-1) as their point of intersection a) y=3x-10 y=x-1. b) y=3x-10 y=2x-7 c) y=5x-16 y=x-4

B) y = 3(3) -10

y = -1

y = 2(3) - 7

y = -1

B satisfies all conditions

C) y = 5(3) - 16

y = -1

y = (3) - 4

y = -1

C satisfies all conditions

Step-by-step explanation:

b. astronomers

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
