Question

Write the equation of the line in slope intercept form give me that F(0)=9 and f(1)=6

Answer 1

Slope intercept Form: y=mx+b

One Point is: (0,9)

Second Point is: (1,6)

First find the slope: m=(y₂-y₁)/(x₂-x₁)

m=(y₂-y₁)/(x₂-x₁)

m=(6-9)/(1-0)

m=-3/1

m=-3

Next we need to use point slope form to get the equation of the line

Point slope form is: y-y₁=m(x-x₁)

y - y₁= m (x-x₁)

y - 9 = -3 (x-0)

y - 9 = -3x

y = -3x +9
