Question

Could someone please help with these two questions (I WILL MARK BRAINLAST)

question 1: which of these points lies on the line y = -x + 2


question 2: evaluate: -ab-a if a=-4 and b =-5​

Answer 1

1. b

2. -16

Explanation:

1. -1+2 is equal to 1 so it works

You plug in each of the coordinates x and y variables on the graph and find one that satisfies the equation.

2. -(-4)(-5) is -20

-(-4) is = 4

-20+4 is -16
