Question

Find the linear approximation of the data that passes through the points (5, 3) and (20, 6)

y = 15x + 9
y = 15x + 3
y = 1/5x - 1
y = 1/5x + 2

Answer 1

To find the slope use \[(y2-y1/x2-x1)\]

Answer 2

(6-3/20-5) = (3/15) = (1/5) is the slope

Answer 3

so A and B is eliminated

Answer 4

i think i had this question be4

Answer 5

i think c

Answer 6

Then plug in points

Answer 7

3=1/5(5)+b, 3=1+b, b= 2

Answer 8

So the correct answer is D not C
