Question 700414: Please help me to solve this:
1. Using the slope-intercept form of a line, find the equation of the line with slope 3/2 and
y-intercept –2. Then graph the line and explain how you determined your graph.

Thanks.

You can put this solution on YOUR website!
y=mx+b is the slope intercept form of a line. m is the slope and b is the y intercept. Plug in the values given: m=3/3 and b=-2:


y = 3/2 x -2.


Graph it by determining two points on the line, then connecting them.


One point is (0,-2) - that's the y intercept. It's the y value when x = 0.


Pick an x value. Plug it into the equation. Find the y-value. That gives a second point.


Use x=1. Then y = 3/2 * 1 -2 = 3/2 - 2 = 3/2 - 4/2 = -1/2. That second point is (1,-1/2).


Draw the points, connect them with a line.
