Point Slope & Slope Intercept 2

Today in class we did point slope and slope intercept again. We also did problems on a white board. Mr. S just mainly gave us something like this: 3/4; (0,2). Then we would have to turn it into point slope form and graph it. So if we were to change this into point slope form it would look like this: y - y1 = 3/4 (x - x1). The original form of point slope is y - y1 = m (x - x1). So all I did was subsitute "y1" with 2 and "x1" with 0 and m with the slope 3/4. After you do all the math then you would end up with y = 3/4x + 2 or in slope intercept form. Then on the white boards we would graph it. So starting from the point (0,2) I would go up 3 and across 4. Why? Because 3/4 is y/x and rise/run. Since y is the rise we would go up 3 and x is the run then we would go across 4. We would start from (0,2) becuase that is a given point and when we graph it we can find the y-intercept.
