I don't quite get this math problem. I'm not too good with slopes and whatnot. Any help would be appreciated! Thank you!

In any equation in the form
y = ax + c where a is the coefficient of x and c is a constant
the slope is always the coefficient of x and the y-intercept is the constant
In your problem,
y = 2/3x + 3
The slope is 2/3 and the y-intercept is 3
y-intercept is the value you get when you substitute 0 in the value of x
y = 2/3x + 3
y = 2/3 (0) + 3
y = 0 + 3
y = 3
The x-intercept is the value you get when you substitute 0 in the value of y
y = 2/3x + 3
0 = 2/3x + 3
0 - 3 = 2/3x + 3 - 3
-3 = 2/3x
-3(3/2) = 2/3x / 3/2
-9/2 = x
x = -9/2 or 4 1/2 or 4.5
To get the slope and y-intercept, be aware of the sign.
If y = -1/5x - 5
The slope is -1/5
the y-intercept is - 5

The slope - interecept general equation is
y = mx + b
Whre m is slope and b is y interecept. The y intercept is defined as the result of the equation when x = 0.
Your equation y = 2/3x + 3
The slope m = 2/3
The y interecept (b)
When x = 0, y = 3
So the y interecept, b, is 3

the slope = 2/3 and the y intercept is 3
in these type of equations: y = Ax +B
A = slope
B = y-intercept
there easy! now you can do them all
