Write down everything you know about the equation y=mx+b. you should include what this general equation represents, as well as what each of the different letters represents. be as thorough as possible.
!

Y=mx+b Is Used To Find Slope Or Is The Slope Formula In General If I Understand Correctly. mx Is Basically Your Slope And b Is Your y-intercept. So Lets Say b Is 9, You Would Go To (0,9) And Make A Point, And Lets Say mx is 3, Which Will Be 3x. So You Would Do Rise Over Run (3 over 1). Go Up 3 And Go To The Right (since 3 is positive) 1 And Keep Repeating Till Your Graph Stops, then You Would Do The Same Thing But Instead Goind Down (negative). So You Would Go Down 3 from (0,9) and Left 1 and Then You Would Draw A Line Through It.

I dont know If I Helped But Yeah..
