Question

Write formula for f(x) in slope intercept form

Answer 1

f(x) = 1000x + 3000

Explanation:

the point (0,3000)

p2 (1,4000)

slope = (y2-y1) / (x2-x1)

= (4000 - 3000) /( 1-0)

slope = 1000 = m

y = mx + b

y=1000x + b

Use one of the points to find b :

3000 = 1000(0) + b

b = 3000

f(x) = 1000x + 3000
