Step-by-step explanation:

To find the slope, you need to use the following equation:

For x₂ and y₂, I picked 5 and 20.  For x₁ and y₁, I picked 3 and 12.  It doesn't matter which points you pick to plug in.  You will get the same answer regardless.  

Your slope is equal to 4.

If you need me to clear something up, let me know.  Hope this helps! <3

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

answer: it's d
