The equation for working out the slope of a linear line is: 
, where x and y are the coordinate pairs.
So just pick two of the purple dots on the graph and fill in the equation.
I'll pick the dot that's (-4, 1) and (4, -7).
Now I just do 
, which is just 
when simplified.
Lol hey what do you wanna do whatever you wanna do just follow your dreams and I’m bored to
Answer:
Well the slope seems rather easy to calculate because you already typed it and it is 2.
First we must solve this equation:
b = y - m*x and we input values into the equation:
b = (3) - (2 * -1)
b = 5
Then, we enter the value of "b" and the slope into this equation:
y = mx +b
y = 2x + 5
