    Okay, so do you know the basics of solving linear functions?

    Oh my.. Lol, well I'l guess I'll teach you. So you know what coordinates are right? Like x-intercept and y-intercept?

    The equation you're trying to solve is basically finding those, and the slope of the line. the equation is y=mx+b Which is slope-intercept form

    m= slope b= y intercept x= variable Look at the graph and where the line intersects on the y axis (Positive 4) and then the next (x,y) intercept ( In this case it's (-1, 1))

    basically to find a line in \[\mathbb{R}^2\] you need 2 points (or the amount of coordinates for general spaces). So you need to find two points through which the line passes. You know that it goes from \[(-2,-2)\rightarrow(-1,1)\] Now you gotta solve the equation y=mx+b turns out good since you have two points (two equations) and two unknowns (m and b) To find m, just use \[m=\frac{y_2-y_1}{x_2-x_1}\], where those are the respective coordinates y and x of both points we found earlier. Now that you know m, we only need b For this, use y=mx+b and subsitute there (x,y) of either poitns and the m Lets take point (-2,-2) -> -2=m(-2)+b b=-2+2m thats it, so find m then b
