Question 102259: I need help with slopes and intercepts, I am dumb when it comes to math. This is really hard for me. Please HELP!. I heard you guys were the best.
I have to write the equation of the line with given slope and y-intercept. Then graph each line using the slope and y-intercept.
1. Slope: -2; y-intercept: (0, 4)
2. Slope: 5; y-intercept: (0, -2)
3. Slope: ;3/4 y-intercept: (0, 8)
4. In which quadrant(s) are there no solutions for each line?
y = 3x + 2
Please help me!

write the equation of the line with given slope and y-intercept. Then graph each line using the slope and y-intercept.
-----------------------------
The slope-intercept form is y=mx+b:
m is the slope and
b is the intercept
-------------------------

1. Slope: -2; y-intercept: (0, 4)
Eq: y = -2x+4

-----------------------------------------
2. Slope: 5; y-intercept: (0, -2)
Eq: y = 5x-2
graph%28400%2C300%2C-10%2C10%2C-10%2C10%2C5x-2%29
-----------------------------------------
3. Slope: ;3/4 y-intercept: (0, 8)
Eq: y = (3/4)x + 8
graph%28400%2C300%2C-10%2C10%2C-10%2C10%2C%283%2F4%29x%2B8%29
-------------------------------------
4. In which quadrant(s) are there no solutions for each line?
y = 3x + 2

The graph indicates there are no solutions in the 4th Quadrant:
