How do you find the slope of # 3y=x+3#?
1 Answer
Slope:
Explanation:
Slope-intercept form:
If we put the given equation into slope-intercept form, we can identify the slope.
First get
#3y = x+3#
#y = x/3 + 1#
This equation is now in slope intercept form. We must find the slope. We saw at the top that the slope,
#x/3#
It is in the form of a fraction. What do we do to clearly identify the slope? Rewrite the variable term, since
#x/3 = 1/3 times x = 1/3 x#
Now let's rewrite the whole equation.
#y = 1/3 x + 1#
#color(grey)(y = mx+b)#
Look for the number before
If we were to graph the equation and look at the slope that way, it would be the same.
