Stupid Algebra test. I don't understand graphs.... 1. Using the slope-intercept form of a line, find the equation of the line with slope and y-intercept –2. Then graph the line on the grid provided and explain how you determined your graph.

    y = "slope" x +"intercept" y = mx + b y = plug in the slope and the yint to define the particular rule

    to graph; but a dot on the y axis that has the same number is the y int. then move in the directions that the slope tells you to move \[\frac{move.by\ y}{move.by\ x}\]

    The slope is 3/2

    then from that point it says; move y, +3 and move x, +2 over.

    if you can draw the graph lines; you can move a dot :)

    So, from where you drew it, I want to move it to the correct space, right?

    correct, the y int gives us a starting point; the slope directs us to the next point from there
