Step 1. The slope-intercept from is given as y=mx+b where m is the slope and b is the y-intercept at x=0 or at point (0,b).
Step 2. Put the given equation in slope intercept form.
Subtract x from both sides of the equation
Divide 5 to both sides of equation
Step 3. The equation has a slope m=-1/5 and y-intercept b=2.
Now the slope of for every five unit you go the right, you go one unit down.
To plot the line take the y-intercept at point (0,2). So starting at point (0,2) or x1=0 and y1=2 we go five unit to the right means x2=0+5=5 and 1 unit down means y2=2-1=1. So we have two points (0,2) and (5,1).
I hope the above explanation was useful.
And good luck in your studies!
