Answer:
._. -_- -.- .-. --__--
Step-by-step explanation:
Slope formula
y2-y1/x2-x1
5-3/2-4
2/-2
-1 = slope
y=-1x+b
5=-1(2)+b
5=-2+b
b=7
Your answer:
y= -1x + 7
1) f(x)=2x+6
f(2)=2(2)+6
=4+6
=10
2)f(x)=3x
f(a+1)=3(a+1)
=3a+3
3)f(x)=3x-1 and g(x)=5x+3
f(2)=3(2)-1
f(2)=6-1
=5
g(3)=5x+3
=5(3)+32
=15+3
=18
f(2)+f(3)=5+18
=23.
a+b= 8+24=32
Ab=8 x 24= 192
B/a= 24:8=3
(a+b)²=(8+24)² =64+576+384= 1024
