Find an equation of the line which passes through the point (4,-7) and has a slope of 3.
Using the Point-Slope Form, we get the equation y-(-7)=3(x-4) or, if you simplify y+7=3(x-4) or y=3x-19.
How can you organize all of your assignments?
You can either organize your assignments by class or by the due date. Organizing by class allows you to see which assignments are worth more points in that class. Organizing by due date offers a visual view of your semester. This allows you to see what weeks you have more stuff do and allows you to plan out when to do what assignments.
Find the slope of the line passing through the points (3,4) and (8,15).
Slope=(y2-y1)/(x2-x1). In this problem (3,4)=(x1,y1), (8,15)=(x2,y2). The slope is (15-5)/(8-3) which equals 10/5. When simplifies this equals 2. This means that the slope of the line passing through the points (3,4) and (8,15) is 2.
