Question

1.For f(x)= 5x+1 Find(-4).
a.-19 b.1 c.-21 d. 21

2. Write in Standard form an equation of the line passing through the given point with the given slope.
slope=-8(-2,-2
a.8x+y=-18 b.-8x+y=-18 c. 8x-y=-18 d.8x+y=18

Answer 1

f(x)= 5x+1
f(-4) = 5(-4) + 1

Solve.

Answer 2

a.-19 would this be the answer

Answer 3

f(-4) = -19 is correct

Answer 4

what about #2?

Answer 5

y = mx+b

-2 = -8(-2)+b

-2 = 16+b

-2-16 = b

-18 = b

b = -18

-------------

y = mx+b

y = -8x-18

8x+y = -18


Answer is choice A

Answer 6

just by coincidence, both answers are choice A

Answer 7

Yeah, Thank you for the help.
