Step-by-step explanation:
Question 1 (answer is C)
6 4
5 2
y=mx+b
4= 6m+b
2=5m +b
by subtracting the two equations
m= 2
4= 6(2)+b
b= 4-12
b= -8
y= 2x- 8
then the answer is C
Question 2
the answer is C
the answer is Cbecause the linear function has a power of (1)
Question 3(B)
m= -2
3 5
y=mx+b
5= 3(-2)+b
5= -6+b
b= 5+6
b= 11
y= -2x +11
the answer is (B)
