Answer 2

The true expressions about functions A and B from the options given are :

• Function A has no slope
• Function B has a slope of 0
• Equation of line B is y = - 5

Function A :

Points: (–5, –2), (–5, 7)

Slope = (7 - (-2)) ÷ (-5 - (-5)) = 9 ÷ 0 = 0

From :

• y = bx + c
• b = slope ; c = intercept

We can obtain c, thus ;

-2 = 0(-5) + c

-2 = c

y = - 2

Function B :

Points:(7, –5), (–2, –5)

Slope = (-5 - (-5)) ÷ (-2 - 7) = 0 ÷ - 9= 0

From :

• y = bx + c

b = slope ; c = intercept

We can obtain c, thus ;

-5 = 0(7) + c

-5 = c

y = -5
