Question 1152790: 1. Graph the following equation using the point-slope method. Draw the point from the equation in yellow. Draw at least one additional point in red using the slope. y - 7 = 3(x + 2)
2. At Generic High School, in the year 2001, there were 20 students per every computer. In 2008, there were 4 students per computer. Write two ordered pairs to represent the ratio of student to computer. (Let x equal the number of years since 2000.)
3. Find the slope-intercept form of the equation that goes through these two points.
4. Find the point-slope form of the equation that goes through these two points.
Thank you!

You can put this solution on YOUR website! --------------------------------
1. Graph the following equation using the point-slope method. Draw the point from the equation in yellow. Draw at least one additional point in red using the slope. y - 7 = 3(x + 2)
------------------------------
The equation as given shows you just what you need.
Included point, (-2,7);
Slope, 3.
Use them!

2. At Generic High School, in the year 2001, there were 20 students per every computer. In 2008, there were 4 students per computer. Write two ordered pairs to represent the ratio of student to computer. (Let x equal the number of years since 2000.)
----------------------------------
Points: (1,20) and (8,4)
------------------------------
3. Find the slope-intercept form of the equation that goes through these two points.
-----------------------------
Pick either of the points as reference for a point-slope equation, if this is the form you want.
(This part asked for slope-intercept but starting here in point-slope form)
Do what you need from this.
-----------------------
4. Find the point-slope form of the equation that goes through these two points.
---------------------
Same thing. See above.
