Please explain this. thank you

Below

Step-by-step explanation:

We can just plug in 3 for k and solve :

     x - 1 / 3 = 3

Step 1. Multiply both sides by 3

     x - 1 = 9

Step 2. Move the -1 to the other side and change the sign

     x = 9 + 1

     x = 10

We can check to see if this works :

     10 - 1 / 3 = k

     9 / 3 = k

           3 = k so this is correct

Hope this helps!

step-by-step explanation:

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
