graphing a line with slope 3 and a y intercept -2

Answer 1

Hello, Lucia,

The standard form of the equation for a straight line is y = mx + b, where m is the slope and b is the y-intercept. The vlaues of m and b are provided, so:

y = 3x-2

Answer 2

So, we start at the y-intercept, (0,-2). The slope is known as rise/run. Since 3 = 3/1, we go up 3 and right 1 to (1,1). The next point is (4,2), etc.

Now, if you have a graph with all four quadrants, remember that -3/-1 also equals 3, so you can go down 3 and left 1 to (-5,-1) and again to (-8,-2), etc.

Once you graph at least 3 points, you should have a straight line running through them.

Answer 3

To graph a line using slope use rise/run.
