Question

Can you determine the function an equation

, the slope and y intercept I would hope you can thanks luv

Answer 1

Slope = 3

y intercept = 35

Explanation:

Given

x = time

y = letters that can not be scanned

Also, we have:

`(x_1,y_1) = (15,80)`

`(x_2,y_2) = (45,170)`

The slope is calculated as follows:

`m = (y_2 - y_1)/(x_2 - x_1)`

`m = (170-80)/(45-15)`

`m = (90)/(30)`

`m = 3`

To calculate the y intercept, we need to determine the linear equation using:

`y - y_1= m(x-x_1)`

Substitute values for x1, y1 and m

`y - 80 = 3(x - 15)`

Open bracket

`y - 80 = 3x - 45`

Make y the subject

`y = 3x - 45+80`

`y = 3x +35`

An equation has the general form:

`y=mx + b`

Where

`b= y\ intercept`

By comparison:

`b = 35`
