Question

Hello can anyone help
given g(1)=5 g(5)=17 what formula should I use to figure g(-3)=

Answer 1

5 = m(1) + b

17 = m(5) + b

that doesnt help..... much :)

given 2 points, we can make a line, and the points given are (1,5) and (5,17)

Answer 2

m = y1-y2 / x1-x2

m= 5-17 / 1-5
m = -12/-4 = 3

y = 3x+b

Answer 3

5 = 3(1) + b

5 = 3 + b

obviously b = 2

so our linear eqauation would be:

y = 3x + 2; lets see if g(-3) fits?

Answer 4

y = 3(-3) + 2
y=-9 + 2
y = -7

g(-3) = -7 using out line equation

Answer 5

If they want a different equation; like for a curve, theyll have to give you more than 2 points to begin with... so thats the best I can do.

Answer 6

thank you so much
