Question

On step 2 question 2Find the estimated y intercept. Round answer to the three decimal places.

Answer 1

Take the coordinates of any two points

(1, 94) and (1.5, 91)

x₁=1 y₁=94 x₂=1.5 y₂=91

First find the slope using the formula below:

`\text{slope(m)}=(y_2-y_1)/(x_2-x_1)`
`=(91-94)/(1.5-1)`

`=-(3)/(0.5)=-6`

Next, is to find the intercept,

Substitute x=1 y=94 and m=-6 into y=mx + b and solve for intercept(b)

94= -6(1) + b

94 = -6 + b

Add 6 to both-side of the question

94 + 6 = b

100 = b

The y-intercept is = 100
