Step-by-step explanation:
y = (1 − 3x) / (x − 2)
Set the denominator to 0.
x − 2 = 0
x = 2
There is a vertical asymptote at x = 2.
Take the limit as x approaches ∞ and -∞.
lim(x→∞) y = -3
lim(x→-∞) y = -3
There is a horizontal asymptote at y = -3.
Plug in 0 for x and y.
y = (1 − 3(0)) / (0 − 2) = -1/2
0 = (1 − 3x) / (x − 2) → x = 1/3
There is a y-intercept at (0, -1/2) and an x-intercept at (1/3, 0).

Answer:
-13x+10
Step-by-step explanation:
(4x+5)(x-2)
Multiply each term in the first parenthesis by each term in the second (foil)
Step 1: Expand it by writing out each multiplication. I added a picture showing which order to do it. (go in order of green, red, blue, yellow.) (you can remember this as first, outside, inside, last.)
When you expand it'll look like: 4x⋅x+4x⋅-2-5x-5⋅-2
Step 2: Calculate product
4x⋅x+4x⋅-2-5x-5⋅-2 (for the 4x⋅x it would be written like )
+4x⋅-2-5x-5⋅-2
+4x⋅-2-5x-5⋅-2 (4x⋅-2 becomes -8x) (multiply 4x times -2)
-8x-5x-5⋅-2
-8x-5x-5⋅-2 (-5⋅-2 becomes +10) (multiply -5 times -2)
-8x-5x+10
Step 3: collect like terms
-8x-5x+10 (-8x-5x becomes -13x) (-8x times -5x)
-13x+10 is the most simplified so it should be your final answer
