Y=3 - 1/2x mathswatch help me please plot on graph

Sagot :

Answer:

  see attached

Step-by-step explanation:

Your equation is in slope-intercept form, ...

  y = mx + b . . . . line with slope m and y-intercept b

with m = -1/2 and b = 3.

This tells you the point y=3 on the y-axis is one point on the graph. (That is the y-intercept.) It also tells you the line decreases 1 unit for each 2 units to the right.

  m = rise/run = -1/2   ⇒   rise = -1 for run = 2

So, another point that is 2 right an 1 down from (0, 3) is (2, 2). Your line will go through these two points. Plot them and draw the line through them.
