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 on the grid provided and explain how you determined your graph.

The slope intercept form of a line is

y = mx + b

where m is the slope of the line

and b is the y-intercept.

Here, m = 3/2 and b = -2

So, equation of the line is

$y=\frac{3}{2}x+(-2)\\ \\ y=\frac{3}{2}x-2\\$

We already know one point on the line which is the y-intercept (0, -2).

Now we need one more point to plot the line.

At x = 2

$y=\frac{3}{2}*2-2\\ \\ y=3-2\\ \\ y=1$

So, the other point on the line is (2, 1).

Draw a line passing through these two points.
