In the graphing problem 3y=2x9 m=? b=? What do m and b stand for? How do I solve?

The slopeintercept form of an equation is,
y = mx + b
m = the slope
b = the yintercept
You need to solve your equation for y, for the equation to be in the slopeintercept form.
3y = 2x  9
Divide both sides by 3,
y = 2/3 x  9/3
y = 2/3 x  3
Now, the equation is in the slopeintercept form and you can easily find m and b.
y = mx + b
Your equation,
y = 2/3 x  3
y = 2/3 x + (3)
m = ?
b = ?
