Why are you shouting?  All CAPS is the electronic equivalent of shouting and is both rude and annoying.


The slope-intercept form is 


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ y = mx + b]


Where <i>m</i> is the slope and <i>b</i> is the <i>y</i>-intercept, that is, the point (0,b) where the graph intersects the <i>y</i>-axis.


You are given a point and the slope, so you need to first use the point-slope form to develop the equation.  The point-slope form is:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ y - y_1 = m(x - x_1) ]


Where *[tex \Large (x_1,y_1)] is the given point and <i>m</i> is the slope.


Just plug in the values and then solve the equation for <i>y</i> in terms of everything else.


The slope number is a way of describing the characteristics of a line and is not only a device for graphing.  What your instructor is trying to do is ensure you understand the relationship between a linear equation in two variables and the graph of a straight line.  This is an essential foundation for understanding the concept of a function.  I have a feeling that you look at each new thing you are introduced to as something distinct and separate from everything else you have learned.  Not so.  Everything you have learned in your study of mathematics is interrelated and will remain interrelated to everything you learn in the future.
